ATTENTION !!!
The practical application of these methods in order to steal electricity, water, gas, etc. against the law! Responsibility for this lies only with the intended use of this information!
Unwind counter - last resort!
To reduce the cost of electrification of production and home, it is highly desirable to use tricks to save electricity and use energy-saving technologies.

1. Electronic.

Content: In industrial electrical installations, in socialist times, they always fought for the quality of electricity, namely, they tried to reduce the amount of reactive energy (the parasitic component of electricity). This was achieved by decreasing the angle between the current and voltage vectors, i.e. approximation cos f = 1. The fact is that the majority of industrial power consumers are inductive loads i.e. the current vector lags the voltage vector by a certain angle (up to 90 degrees). Including the capacitive load simultaneously with the main equipment (synchronous compensators or cosine capacitors for voltages from 0.22 to 10 kV), we achieved an increase in cos f. So, in our practice there were cases when at the factory on weekends, when the equipment was running at minimum power, the electrician on duty eating something wrong on Saturday morning, forgot to turn off compensators that are designed for the maximum power of the enterprise. The result was a decrease in the readings of the active electricity meter (induction), it’s good that there is still generation accounting, which subsequently showed the resulting imbalance in head accounting and consumer accounting! And the idea that was in the air was confirmed in practice !!! Another example was in the village of my grandfather, who sawed firewood in the spring of 7.5 kW in the spring, and so, while the grandfather was dragging another birch to the saw, we checked the counter and its disk-rogue slowly rotated in the opposite direction :) and when the chock got into the ruthless teeth of the saw-disk counter began to rotate forward! In short, the idea is wonderful and examples of its implementation are a dime a dozen, but there is one “but”: in order to obtain capacitive power commensurate with the power consumption i.e. To generate power in the network, large capacitors are needed for an operating voltage of 400 V, however, craftsmen from the people here also found a way out! Here is the content of the principle of operation of the obtained circuit:
In the first half-wave of the mains voltage, energy is consumed from the network (keys A and D are open), that is, capacitor C1 is charged, but charged through a transistor switch which is controlled by high-frequency pulses i.e. energy for charging is consumed by pulses of increased frequency (reactive power is consumed cos f = 0, and P = 0 as well, since P = U * I * cos f. The keys C and B are open in the second half wave, since C1 is discharged. Since the voltage on the capacitor is higher than in the network, at the beginning of the second half-cycle, energy is transferred to the network, cos f? 0, and therefore P? 0). It is known that the counters, incl. electronic because they contain an induction current sensor with a magnetic circuit having a limited conductivity in frequency, and induction, because in addition to magnetic, they also contain the mechanical part of the measuring system, have a very large negative error during the passage of high-frequency current. It remains in the second half-cycle, through the other arm of the keys, to discharge the capacitor into the network without any impulses. So for example: they consumed 2 kW, the meter took into account 0.5 W, ideally gave 2 kW, the meter took into account -2 kW. The result of the period is the induction meter spins back at a speed of -1.5 kW, and the electronic one costs up to 1.5 kW.
Advantages: all seals and the meter itself remain unchanged, the wiring also does not change. Grounding is not required. The device is plugged into a regular power outlet, you can work with other power consumers !!!
Minuses: it is necessary to solder the circuit !!!
Economic effect: induction meters reduce their readings by 1-1.5 kW / h per hour, while electronic meters stop (i.e. underestimate) as much! That is, the scheme inherently represents a device for unwinding induction meters without ratchet (i.e., you can turn it on without a consumer load at night and rewind readings of 10-15 kW / h) and stop all other meters when the consumer load is applied (for example, simultaneously with heating!).


2. The rewind generator.

Contents: The device is designed to unwind the readings of induction electric meters without changing their switching circuits. With regard to electronic and electronic-mechanical meters, the design of which is incapable of counting down the readings, the device allows you to completely stop the metering to a power consumption of several kW.
A device assembled according to the proposed scheme is simply inserted into a socket and the counter starts counting in the opposite direction. All wiring remains intact. Grounding is not necessary. The operation of the device is based on the fact that the current sensors of electric meters, including electronic ones, contain an input induction converter having low sensitivity to high-frequency currents. This fact makes it possible to introduce a significant negative error into account if consumption is carried out by high-frequency pulses. These factors allow you to create a generator simulator. The main element of such a device is a capacitor of the appropriate capacity. The capacitor for a quarter of the period of the mains voltage is infected from the network with high frequency pulses. At a certain value of the frequency (depending on the characteristics of the input converter of the meter), the meter takes into account only a quarter of the actually consumed energy. In the second quarter of the period, the capacitor is discharged back into the network directly, without high-frequency switching. The meter takes into account all the energy that feeds the network. In fact, the energy of the charge and discharge of the capacitor is the same, but only the second is fully taken into account, creating an imitation of the generator that supplies the network. The counter then counts in the opposite direction with a speed proportional to the difference per unit time of the discharge energy and the taken into account charge energy. The electronic meter will be completely stopped and will allow the energy to be consumed without consideration, no more than the value of the discharge energy. If the consumer’s power is greater, then the meter will subtract the device’s power from it. In fact, the device leads to the circulation of reactive power in two directions through the meter, in one of which full metering is carried out, and in the other partial.
Disadvantages: you need sufficient knowledge of electronics both in manufacturing and in customization.
Advantages: all seals and the meter itself remain unchanged, the wiring also does not change. Grounding is not required. The device is plugged into a regular power outlet, you can work with other power consumers !!!
Economic effect: With the elements indicated on the diagrams, the device is designed for a rated voltage of 220 V and a winding power of 2 kW.
Comment (!): The circuit is fully operational, we tested in practice.


3. The method of "Phase"

Content: for the most energy-consuming electrical receivers (electric boilers, electric heaters, electric stoves), an individual electrical outlet is provided, or, when using the above-mentioned electrical appliances, the whole house is connected in such a way that the consumed electricity is not completely taken into account by the electric meter. The method is based on the design features of all (!) Electric meters. It is carried out within 10-15 minutes without interference with the internal mechanism of the electric meter, with the safety of all seals on the electric meter. To do this, slightly change the input circuit (5-10 min.) In some cases and do not (especially in rooms with Euro outlets), a screwdriver and a piece of cable (1-1.5 m) with a socket are needed. In the executed form, there is the possibility of unlimited (!) Energy consumption either through this outlet or in the entire house, without changing the meter readings.
Advantages:! the easiest to execute! (even a child can do it), suitable for any electric meters, the possibility of detection is practically excluded since all electrical appliances connected to a socket other than the above will be counted by the electric meter (the disk will spin, the indicators will blink) in our memory from hundreds of intruders, such units have been detected, there are no restrictions on the size of consumption and connected electrical appliances (only the cross-section of the lead-in conductor). In our top, he is one of the first! For employees of energy supply organizations, as consumers of electricity, this method is the most popular !!! :)
Disadvantages: only for single-phase meters.
Economic effect: up to 100% of consumed electricity is not taken into account.


4. The method of “Zero +”

Content: the method is based on the principle of electricity metering implemented in all (!) (Induction and electronic, single-phase and three-phase) meters. It is carried out without interference with the internal mechanism of the electric meter, with the safety of all seals on it, only access to it is necessary (the best solution for residents of high-rise buildings). In fact, this solution to the problem - to stop the counter, turned out to be the simplest and most ingenious at the same time! The answer to the question was so visible that it is difficult to imagine at first. We ourselves did not believe for a long time, until we encountered its implementation in practice.
Now the method is suitable for absolutely all metering schemes: single and three phase, induction and electronic meters. In general, the method is very beautiful and quite simple. Electronic components are not required.
Single-phase metering: When executed, there is the possibility of unlimited (!) Energy consumption throughout the house, without changing the meter reading.
Three-phase metering: In the executed form, there is the possibility of unlimited (!) Electricity consumption in one phase, without changing the meter readings.
Advantages: the most effective and safe !!! the seals and the electric meter itself remain unchanged, simplicity of execution, suitable for any electric meters, the possibility of detection is excluded, in our memory, out of hundreds of intruders, one is installed (!), (in truth, after its detection, we completely changed our views on electricity metering and this with an experience of about 10 years !!!) there are no restrictions on the size of consumption and connected electrical appliances (only the cross section of the lead-in conductor). In multi-storey buildings, it takes about an hour. He is the first in our top! The method is almost unknown to employees of energy supply organizations !!!
Disadvantages: none !!!
Economic effect: up to 100% of consumed electricity is not taken into account.


5. The “Transformer” method (for 1-f. And 3-f. Counters)

Contents: when the electric meter “clocked” a sufficiently large number of kW / h, its readings can be reduced (rewound). In fact, the method describes a circuit of a device for rotating the meter disk in the opposite direction, as well as a circuit for connecting it. The method is based on the design features of induction electric meters. It is carried out without interference with the internal mechanism of the meter, with the safety of all seals on the meter.
Single-phase metering: for the implementation, the input circuit is slightly changed (5-10 min.) In some cases, and they don’t do this, and they also make the simplest device - a transformer, with the help of which they decrease the readings (twist the drums of the counting mechanism in the opposite direction) of the electric meter. The current flowing through the current coil of the electric meter is approximately 10 amperes, which corresponds to a decrease in its readings by 2.2 units (per night - 20 kW \ hours, per month - 600 kW / hours).
Three-phase metering: contrary to the widespread belief that a three-phase meter cannot be “rewound”, a method was discovered in our practice that we ourselves could not believe, but this is a fact, and it is a very stubborn scoundrel. To implement it, you need access to the input to the electric meter (terminals of the machine or knife switch (in our case we used an input machine of the AP-50 type), or a break in the input cable), they also make the simplest device - a transformer, with which the readings are reduced (twisting drums of the counting mechanism in the opposite direction) of the electric meter. The current flowing through the current coil of each phase of the meter is approximately 10 Amps, which corresponds to a decrease in its readings by 6.6 units per hour (per night ~ 55 kW \ hours, per month ~ 1600 kW / hours).
Pluses: a practical choice! after the manufacture of the transformer, the ability to use an almost unlimited number of times. The method of use in three-phase metering for many employees of energy supplying organizations is unknown since considered unreal !!! :) )) In ours, he is one of the first.
Disadvantages: it is necessary to manufacture a transformer, it is not suitable for electronic electricity meters and electric meters with a stop (ratchet is shown on the panel, and during rotation of the disk, clicks are heard like clock ticking, only much less often).
Economic effect: per month ~ 600 kW \ hour for single-phase and ~ 1600 kW \ hour for three-phase meters, electricity is not taken into account (depends on appetite :) )


6. The “Starter” method

Content: on the input cable, to the meter, a gap (box) is made from which one end goes to the meter, the other to the magnetic starter (rated current depending on the load, usually 25 Amperes or more), through the starter they feed whatever your heart desires (heating system , electric stoves, saunas, etc.), while providing for the possibility of connecting them through an electric meter (in case of verification). The control circuit of the starter (the “start” and “stop” buttons) is powered from the mains at home, through an electric meter in a convenient place for quick disconnection (again in case of checking). There were times when the buttons were disguised as interior elements: pictures, hangers, watches. When checking, the voltage from the load through the starter is removed and the voltage indicator of the tester does not show anything, the starter itself is carefully masked, and the wiring is placed in a metal sleeve (a good screen for voltage indicators) and plastered or sewn up with lining. Often, from a break (box), the load is connected directly, without a starter, in this case, the probability of detection by the “left” wiring is increased many times (now all the personnel of the power supply organizations are equipped with voltage indicators, a regular receiver at 50 Hz, it shows the presence of hidden wiring to a depth of 4 see if it is not shielded).

Advantages: the ability to use an almost unlimited number of times, the difficulty of detection, all seals and the electric meter itself remain without damage. Suitable for three-phase metering. In ours, he is one of the first.
Disadvantages: the need to install additional wiring and violation of the integrity of the input cable (detection capability).
Economic effect: cases were discovered when a consumer “saved” about 10,000–13,000 kW / h per month.


7. The method of “Cremation of the voltage coil”

Contents: using the simplest circuit, which is connected to a conventional outlet, in induction three-phase meters, the voltage coil of that phase from which the aforementioned outlet is powered is disabled. The method is quite extreme and requires the presence of spirit. watch for an hour at a smoking counter occasionally scattering sparks from liquid metal (all that remains of the voltage coil) not everyone has the nerves! A joke, of course! :) The process of failure of one meter element takes a maximum of 2 minutes. This is achieved, as the name implies, by burning one or more voltage coils by applying an increased voltage from the above device. All diodes are 1000V / 1A, all the conductors are 50 μF each (as you can see, two of them are connected in series!). Use imported Conders, Soviet explode. VU - this is the rectifier-voltage multiplier, which is turned on after the counter in one of the sockets of the consumer network. A diagram of it below the connection diagram of the WU to the meter.


Advantages: the circuit is simple, it is connected to a conventional outlet, all seals on the meter and on the input switching device remain unchanged.
Disadvantages: after using this device, one element fails irrevocably i.e. It is not possible to restore a dead voltage coil without opening the meter.
Economic effect: one third (with a symmetrical load) or more (if you load the phase in which the voltage coil burned out), electricity is not taken into account.
Comment (!): Not so long ago, one of our colleagues from the same Baltic states - pastas5kv, told us the following that this method is also suitable for electronic meters (including the most sophisticated from ABB (Germany)). The essence of his comment is as follows: during the cremation of 2 phases in a three-phase meter, the metering of electricity still continues by 100%, because voltage to the counter controller comes from a single “healthy” phase. If you turn it off, then the accounting will stop, even if there is a load on two “cremated” phases! The indication on the meter will be the same as if the voltage had disappeared at all in the mains. Thus, it turns out that after cremation, it is possible to use one or two phases without taking them into account with an electric meter, it is only necessary to disconnect, respectively, two or one “working” phases. And another comment from pastas5kv: high voltage can not be applied immediately to the maximum, it must be applied several times starting from a small level and gradually increased until an insulation breakdown and the voltage coil fail. According to the author, if cremation is done correctly, then a failed coil externally practically does not differ from a working one.


8. The method of "tilt angle"

Content: the method is based on the design features of induction electric meters. It is carried out without interference with the internal mechanism of the meter, with the safety of all seals on the meter. The electricity meter, together with the shield on which it is mounted, is tilted up to 90 degrees relative to the ground (as a rule, the shield is either on the hinges in the upper part or the shield fasteners can be easily removed). When the meter “lies on its back”, its disk stops rotating regardless of the load connected through it. Actually the disk stops spinning already at 40-60 degrees
Advantages: the ability to use an almost unlimited number of times, ease of execution, all seals and the electric meter itself remain without damage. Suitable for three-phase metering. In ours, he is one of the first.
Disadvantages: not suitable for electronic electricity meters, a lot of fuss with setting the desired angle, with a sudden check it is easily detected.
Economic effect: per month up to 100% of electricity is not taken into account.


9. The method "Measuring circuit" (includes four methods)

Contents: If in direct-connected electricity meters (up to 100 Amperes), the measuring circuits are built-in inside the case (many electronic transformers have current transformers - a bus and a winding, nothing special), then electric meters designed to account for electricity of large consumers (operating currents from 100 Amperes and above), part of the metering circuit is installed outside the meter body - current and voltage transformers (for metering in circuits of 10 kV and above). There are several schemes depending on how the accounting is organized, whether the measurement circuits are sealed, which input switching device, where the transformers are installed (on RP, TP or ZTP, in ASU). In our practice, hundreds of schemes for under-accounting of electricity have been discovered, but they are not fundamentally different, there are four main methods, the difference is only in performance. 1). Shunting the secondary of current transformers 2). Change the polarity of current transformers 3). Disconnect the voltage coil of the electric meter 4) Shunt current transformer

All manipulations are performed on the terminals of current transformers. This requires free access to the transformers themselves, or (if there is) access to the test block (installed to the electric meter). The big problem is whether the transformers and the test block are sealed, no. As a rule, both are not sealed. The worst option is when the entire electricity metering board is sealed, then basically - Bummer. Secondary filling is performed using plastic caps (mold or factory). However, there is always a distance between the wires and the cap itself, into which the shunt is inserted (an ordinary bracket from a wire with insulation and bare ends to a length that would be enough to touch the contacts of the secondary). If CTs (current transformers) are not sealed, then a freebie: disconnecting the input circuit breaker or circuit breaker (it is impossible to energize - if you open the secondary circuit, then under the induced potential, a breakdown may occur), unscrew the screws securing the secondary wires and insert the same clip the shunt itself (see above). TT polarity reversal is performed only on unsealed secondary leads. It is carried out elementarily: the screws of the securing of the secondary wires are unscrewed and they are interchanged (wires essno!). Manipulations are carried out with relieved tension (see above). The disconnection of the voltage coil conductor is also performed on unsealed CTs. Again, having removed the voltage from the CT, using a conventional wrench (usually 14 (13) or 17), unscrew the nut of the "tension" wire and the latter is removed. You can then put between the wire and the nut put the washers poorly conducting electric current, they can simply be painted at the point of contact, or well pierce the bare end of the wire (again, worsen the contact!), And install the wire in place. Shunting of the CT itself is also quite simple, by disconnecting the input circuit breaker (knife switch, bag, etc.), with the help of "crocodiles" a conductor of good cross section (with essno insulation!) Is fixed to the CT and after the CT, it can be performed in all phases. The method is applicable in some cases when the entire metering board is sealed. In our top, he is one of the first.
Advantages: all seals and the electric meter itself remain unchanged.
Disadvantages: in any case, an initial knowledge of electrical engineering is necessary for the competent collection of the circuit. Constant monitoring of accounting is necessary, time is needed to parse the circuit (in some cases).
Economic effect: from 30% to 100% of unaccounted for electricity consumed (the figure of 100% really contradicts common sense). In our practice, cases have been discovered with a decent underestimation of electricity, for example: about 30,000 kW \ hours per month (flour mill) and 80,000 kW \ hours per month (cookie confectionery production line), and many others like them. At the same time, consumers have been using this method for more than one month. There are 4 (!) Schemes for its execution.

10. The “Shock” method (includes three methods)

Content: the method is based on the design features of electronic electricity meters. It is carried out without interference with the internal mechanism of the meter, with the safety of all seals on the meter. There are three ways: 1) for SET type electric meters (a case was discovered), it is tightly “wrapped” with black polyethylene and in hot weather it fails after a while, as a rule it starts to “self-propel” at a high speed (they say, it can stop) which is subsequently established by verification.2) for meters of the type CE6807B (with LCD panel), but it will also work for others: they bring “electric shock” close to the electricity meter (used for self-defense) and turn it on several times until the indication on the panel is reset. 3) the most extreme: provided that there is good wiring (decent cross-section) and automation, they turn on the maximum allowable load for the electric meter (for example, welding) in jerks with short interruptions, as a rule, one or several built-in current transformers fail (the secondary burns out).
Disadvantages: only suitable for electronic electricity meters, mostly single use
Economic effect: in each case in different ways, it is difficult to predict.


11. The method of “Shunt counter”

Content: the method is quite trivial, its essence is as follows: the so-called shunt is mounted from the input switching device to the load switching devices, which is a piece of wire of the required length. In its completed form, with the input device turned on, most of the consumed electricity is not taken into account, but if this device is turned off (and the shunt is connected energized to the supply contacts of the input device), then all the consumed electricity is not taken into account. The easiest way to do it is in apartment shields (on stairwells), because in most cases there is free access to both the introductory (as a rule, this is an ordinary packet) and load (two or more circuit breakers) switching devices. Having turned off the input device (turn the handle of the bag by 90 degrees), check the absence of voltage at the outgoing contacts (using a standard screwdriver - “probe”), cut off the wire (with essno insulation!) Of the required length, strip it from both ends and then fix one end to the phase outgoing contact of the bag (under the screw, the bare end is formed into a “ring”), the second end to the phase contact of the load automat. That's all done! The bag turns on by turning the handle 90 degrees. and the circuit is ready for operation. In the shield, the shunt is masked and all switching devices are closed with a protective panel (which was removed before installation :) ) Inspectors look inside the shield at best once a century (especially if the house is 9 or more floors).
There are even simpler options when the shunt is carried out directly in front of the meter terminal block, either by stripping the insulation of the generator and load phase wires, and then shorting them (directly between each other or using a piece of wire), or by “slipping” a piece counter under the terminal block cover wires in the form of a bracket in the holes between the 1st and 2nd terminals (where the generator and load phase wires are initially mounted).
Disadvantages: if the testers once look at the protective panel that hides the contacts of the bag and vending machines, then the trick is easily detected.
Economic effect: if you only shunt by phase, the meter underestimates up to 50% of the consumed electricity, if you bypass and zero, then 100% of the underestimation is guaranteed.


12. The method of "Friends"

Content: the method is used, as a rule, in cases where one consumer has 1-f on his balance sheet. counter and 3 f. counter (power), or when the neighbors are on friendly terms (then they manage what is called “exchange phases”). In any case, two counters are required. The bottom line is: a phase is taken from one counter, and zero from another. In the case of using 1-f. and 3 p. counters, the phase is taken from 1-f., and zero from 3-f. At the same time, they do not forget to conduct phasing before switching the wires (that is, connect the phase from one meter to the network (socket) of another meter to the phase contact (find out with a screwdriver “probe” in advance), and zero, respectively). In the scheme 1-f. the counter from which the phase is taken, you need to make input changes (change the phase and neutral wires in places) and disconnect the zero switching device. In the circuit of the second counter, the phase switching device is switched off.

Disadvantages: basic knowledge of electrical engineering is needed since it is necessary to make changes on input 1f. meter, mount additional wiring.
Economic effect: up to 100% underestimation of electricity is guaranteed.


13. The method of "Screw voltage" (includes two methods)

Content: with two screws, through the top of which either a fishing line or wire is threaded onto which the local power supply organization installs its seal, excluding consumer access to the terminals of the electricity meter. The essence of the method is as follows: the above seal is removed, the cover fastening screw (s) is unscrewed, and here it is - the terminal. Wow! What now? And now the consumer, using a screwdriver with an insulated handle, carefully 1) unscrews the voltage screw (it is easy to identify, he fastens a small jumper about 1 cm long on the left side of the terminal block) until the meter’s disk stops or it stops blinking (if the meter electronic). Yes, by the way, some consumers with the cover removed 2) change two wires from the first and second terminals in places, the effect is impressive - the meter dial rotates in the opposite direction, and the electronic one stops (though meters (eg “Solo”) began to appear, which consider electricity and in this case). Now it's time to put everything in place: the cover, screw (s) and ... the seal, which is installed as in the previous method.

Advantages: the effect is instantaneous or if a washer from a poor electrical conductor is installed under the voltage jumper (paint with varnish or graphite grease), prolonged.
Disadvantages: as in the previous method, deformed and fake fillings in 90% of cases are very easily determined.
Economic effect: up to 100% of consumed electricity is not taken into account.


14. The method of "voltage jumpers" (includes two methods)

Content: the terminal block of the three-phase electric meter is closed by a cover, which is fastened with two screws, through the top of which either a fishing line or a wire is inserted through which the local power supply company installs its seal, excluding consumer access to the electric meter terminals. The essence of the method is as follows: the above seal is removed, the cover fastening screw (s) is unscrewed, and here it is - the terminal. Wow! What now? And now the consumer, using a screwdriver with an insulated handle, carefully 1) unscrews the screws of the voltage jumpers (they are easy to identify, they are installed between the 1st and 2nd, 4th and 5th, 7th and 8th terminals of the long about 1 cm), until the meter’s disk stops or it stops blinking (if the meter is electronic). Yes, by the way, some consumers with the cover removed 2) change two wires from the 1st and 3rd, 4th and 6th, 7th and 9th terminals in places, the effect is impressive - the meter dial rotates in the opposite direction side while the electronic one stops. Now it's time to put everything in place: the cover, screw (s) and ... a seal that is carefully threaded through a fishing line or wire, after threading the latter through the screws that secure the cover, and then squeezed with anything (pliers with a rag on the lips (to leave no residue), fake sealants, etc.).

Advantages: the effect is instantaneous or if a washer from a poor electrical conductor is installed under the voltage jumper (paint with varnish or graphite grease), prolonged.
Disadvantages: as in the previous method, deformed and fake fillings in 90% of cases are very easily determined. Employees of energy supply organizations: be careful, carry a flashlight and a magnifying glass with you!
Economic effect: up to 100% of consumed electricity is not taken into account.


15. The method of “nameplate transformer”

Content: mainly new consumers apply, the essence is this: on a current transformer, for example 300/5, a nameplate (information panel) is installed from the transformer with a lower coefficient, for example from 100/5. As a result, a smaller coefficient is involved in the calculations for the consumed electricity.
Advantages: very easy to execute, the electric meter itself is not worried.
Disadvantages: during verification they can detect (rarely).
Economic effect: depends on appetite


16. The method of "Slit"

Contents: Between the glass and the casing of the meter, by pressing or gouging out (do not pick a synonym) glue, a micro-space is formed that is sufficient to push a strip of thin but strong material (usually film) about 10 cm long and 1 cm wide, until the meter’s disk touches, which at the same time stops its movement.

Advantages: the effect is instant, you can use it repeatedly, as before a coin on a thread for a pay phone. Suitable for three-phase metering.
Disadvantages: upon careful examination of the glass and the casing of the meter, it is very easy to detect (the gap itself is visible, and as a rule scratches and fingerprints remain on the glass (from big traffic :) )). It happened that after disassembling such a counter, inside were the nudges of the consumer himself :) )) Suitable only for induction electric meters (they have something to stop - the disk!).
Economic effect: up to 100% of consumed electricity is not taken into account.


17. The method of "Hole"

Contents: a hole is made in any place of the casing of the electric meter (right, left, top, bottom, from the back (through the wall on which the electric meter is installed), behind the ledge of the casing (the rim around the perimeter of the electric meter is 1-2 cm from the back)) as possible inconspicuous and an object is inserted into it such as a knitting needle or needle (preferably from a dielectric material: plastic or wood) of such a size that it reaches out to the counter’s disk, and as soon as it reaches, the electricity meter turns from a megabyte into a piece of carbolite with a filling even ck does not rotate. There have been cases in history when the hole was detected only at the time of delivery of the electric meter, replaced by the deadline, to the warehouse (it was done in jewelry, the mosquito of the nose will not undermine!).

Advantages: the disk of the electric meter does not rotate, so what? That's right, the readings do not change, money is saved (for example, on new boots or a ticket for Penkin in the front row). Suitable for three-phase metering.
Disadvantages: not suitable for electronic electric meters (although some consumers tried to make a hole to stop the stop of the stepper motor (opposite to the counting mechanism on the right side near the last drum) is too noticeable), for the most part it is easily detected, it is not very easy to restore the integrity of the casing of the electric meter (although putty , skin and kuzbass varnish, here they are “crazy hands”).
Economic effect: up to 100% of consumed electricity is not taken into account by the electric meter.


18. The method of “Seal of state verification” (includes nine methods)

Contents: the cover of the electric meter is fixed to the base with two or three screws, through the upper part of which (usually two), either a fishing line or a wire (sometimes protected from damage like Silvire LG9 type) is threaded onto which the state inspector (or the manufacturer) installs the seal so thereby confirming that the device is suitable for operation (it works in the measurement class, there is no self-propelled device, etc.). Without removing this seal, access to the internal mechanism is impossible (as a rule!). These seals are carefully (as much as possible) removed, the screws securing the casing are unscrewed, the casing is removed. Hooray! Do with a counting mechanism, or with a voltage coil, or with current transformers (for electronic electric meters) or with an information panel that the soul will wish (and she wants only to save pieces of paper with watermarks). There are several ways: 1) using a screwdriver, twist the disgusting numbers on the drums of the counting mechanism back, 2) solder the resistance into the circuit of the voltage coil (differs from the current coil by a much smaller cross-section) or 3) the reed switch (in the future, bringing the permanent magnet to the meter, it stop), 4) change the information panel to another (for CO-I446 counters, install 10-34 Ampere on the counter (five windows are cut on it), a panel from 5-17 Amperes (four windows are cut on it) i.e. instead of units are considered tens of kW \ h, 5) bite out a part of the teeth of the counting mechanism (on tens and hundreds, the second and third drums), usually through one tooth, etc. 6) solder the shunt into the circuit of the current coil (especially relevant for electronic meters, current transformers are shorted there), 7) tighten the screw of the permanent magnet, bringing it closer to the disk (brake the disk), 8) weaken the coupling of the gear of the counting mechanism with the worm of the disk axis, 9 ) reduce the number of turns of the current coil of the meter. All this ultimately leads to an underestimation of electricity, but the time comes to assemble the designer: put the casing in place, tighten the screws and oh, mom !!! And what to do with fillings? Himself filmed, himself and pretend. First, the seals are carefully put on a fishing line or wire, then squeezed. Yes, I almost forgot, many consumers in a hurry put the casing of the electric meter as it should, but you need to put it as it was - with the tabs up. When crushing the seals, everything is used: pliers with a rag on the lips (so as not to leave marks), seals, fakes, etc.
Advantages: instant effect (in the case of twisting the drums with a screwdriver) or prolonged (shunts of the current coil (current transformers), reed switch and resistance in the voltage coil circuit, replacing the information panel or biting part of the teeth of the counting mechanism). Suitable for three-phase metering.
Disadvantages: deformed or fake fillings are very easily identified (in 90% of cases). Employees of energy supply organizations: be careful, carry a flashlight and a magnifying glass with you!
Economic effect: twisting the drums of the counting mechanism - up to 100% of the consumed electricity excluding, shunt of the current coil - it is possible to achieve 100% of the unaccounted electricity, reed switch and resistance - from 30 to 100% of the electricity is not taken into account.


nineteen . “Direct current” method

Contents: A significant increase in the negative error of induction electric meters can be achieved by passing a direct current through their current coils, which will make a magnet from the core of the current coil. The magnet, in turn, causes braking of the electric meter disk. A similar (permanent) magnet is in every induction electric meter. Additional magnet - additional braking. To simply supply direct current through current coils, two meters are required connected to the same phase. You can, for example, cooperate with a neighbor, or, under any pretext, issue an additional counter. The secondary winding of the transformer should produce a small voltage of ~ 5 V, such that the current is equal to twice the rated current of the meter. It is selected experimentally. The inductor is optional, it allows you to record electricity separately along the circuits, and also smooths the ripple of the rectified current. The number of turns should be small to avoid saturation of its core. In this way, it is possible to reduce the counter stroke by ~ 30%.
Disadvantages: one more phase is needed and it is necessary to produce a circuit
Economic effect: up to 100% underestimation of electricity is guaranteed.


twenty . The method of "sprout"

Contents: for Rostock SOE-5020H electric meters, but also suitable for everyone on the ADE77XX. The counter does not know how to immediately count the active power, so it assumes that the total power is equal to the geometric sum of the active and reactive powers. An electric meter measures total power and reactive power, and of these two capacities it finds active. Here is the basis of the method - it is enough to make the meter count the reactive power very large and then the meter stops. How to do it - it turns out after 5 reads of the datasheet on the AD7751. For the manufacture of the device, a handful of any electronic trash with a total cost of about 4-5 cu is enough.
Disadvantages: sufficient electronics knowledge needed
Economic effect: up to 100% underestimation of electricity is guaranteed.


21. The method of "Electric heating"

Content: It is no secret that modern household appliances are quite economical, and paying for the energy consumed by it is not such a heavy stone on the neck of citizens. Another question is the electric heater (fireplace, sauna, thermal curtain at the entrance of the store, electric boiler, water heater, etc.) - why should I pay for heating? And if I am heated, what should I pay for it ??? Absurd! Let's learn how to use an electric heater for free. Using our circuit, you can turn on the electric heater in a socket completely invisible to the meter. I will say directly - you can connect any electrical device that is not demanding on the form of the supply voltage. How does this circuit work? After turning on the power, the mains voltage is supplied simultaneously to the diodes VD1 and the primary winding of the transformer T1. If at the moment of turning on the regulator a negative polarity voltage appeared in the network, the load current flows through the emitter-collector circuit VT1. If the polarity of the mains voltage is positive, current flows through the collector-emitter circuit VT1. Well and so on. Thus, our electric heater turned into a high-frequency (from the point of view of the counter) load, and he didn’t like it. After all, it is known that counters, both electronic (they contain an induction current sensor with a magnetic circuit with limited frequency conductivity), and induction (in addition to the magnetic, also contain the mechanical part of the measuring system), have a very large negative error during the passage of high-frequency current. The device is inserted into a conventional outlet through it and the electric heating (fireplace, boiler, etc.) is energized, there is no need to access the meter or input, everything remains unchanged, grounding is not required !!!
Disadvantages: it is necessary to produce a circuit that the truth will collect and configure any beginner amateur radio student :)
Economic effect: up to 100% underestimation of electricity consumed by an electric heater is guaranteed.
