Способы отмотки и остановки электросчетчиков не проверенные (описание)

The following are found on the Internet for untested ways for free. All that was found and not verified is on this page. Below the link we can find and download the schemes themselves.

ATTENTION !!!
Practical application of these methods in order to steal electricity, water, gas, etc. is illegal! Responsibility for this is borne only by using this information as intended!
Counter winding - extreme measure!
To reduce the cost of electrification of production and home, it is highly desirable to use tricks that save energy and use energy-saving technologies.

1. Electronic.

Content: In industrial electrical installations in socialist times, they have 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 reducing the angle between the current and voltage vectors, i.e. approximation cos f = 1. The fact is that a large part of industrial power consumers is an inductive load i.e. the current vector lags behind the voltage vector at a certain angle (up to 90 degrees). Including simultaneously with the main equipment a capacitive load (synchronous compensators or cosine capacitors for voltage from 0.22 to 10 kV) achieved an increase in cos f. So, in our practice, there were cases when at the factory on weekends, when the equipment works at minimum power, the duty electrician having eaten on Saturday in the morning of something wrong, forgot to turn off compensators, which are designed for the maximum capacity 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 later showed the resulting imbalance in the head metering and metering of the consumer! And the idea that was in the air was confirmed in practice !!! Another example was in the village of my grandfather, who in the spring sawed wood on a 7.5 kW circular saw, and so, while my grandfather was dragging another birch to the saw, we checked the counter and its git drive slowly rotated in the opposite direction :) and when the chock fell into the ruthless teeth of the saw-disk counter began to rotate forward! In short, the idea is remarkable and examples of its implementation in life are a dime a dozen, but there is one “but”: in order to get the capacitive power comparable to the power consumption, i.e. To generate power in the network, large capacitors for a working voltage of 400 V are needed, but craftsmen from the people have found a way out! Here is the content of the principle of operation of the resulting scheme:
In the first half-wave of the mains voltage, energy is consumed from the mains (keys A and D are open), that is, capacitor C1 is charged, but charged through a transistor switch that is controlled by high-frequency impulses, i.e. energy for charging is consumed by pulses of increased frequency (the reactive power is consumed cos f = 0, and P = 0 is also meant because P = U * I * cos f. In the second half-wave, the keys C and B are open, C1 is discharged. Since the voltage on the capacitor is higher than in the network, at the beginning of the second half period, the energy is sent to the network, cos f? 0, and hence P? 0). It is known that the counters including. electronic because They contain an inductive current sensor with a magnetic core having a limited conductivity in frequency, as well as induction, because in addition to the magnetic, they also contain the mechanical part of the measuring system; they have a very large negative error when the high-frequency current flows. It remains in the second half period, through the other key arm to discharge the capacitor into the network without any impulses. So for example: consumed 2 kW, the meter took into account 0.5 W, gave ideally 2 kW, the meter took into account -2 kW. The result of the period is that the induction counter turns 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 is also not changed. Grounding is not required. The device turns on in the usual socket, it is possible together with other electrical receivers !!!
Disadvantages: it is necessary to solder the scheme !!!
Economic effect: induction meters reduce their readings by 1-1.5 kW / h per hour, and the electronic ones stop (i.e. underestimate) as much! That is, the scheme is essentially a device for unwinding induction meters without a ratchet (i.e., it is possible to switch on the consumer without overloading at night and unwind the readings to 10-15 kW / h) and stop all other meters with the consumer load applied (for example, simultaneously with heating!).


2. Generator unwinding.

Contents: The device is designed to unwind indications of induction meters without changing their switching schemes. With regard to electronic and electronic-mechanical meters, the design of which is based on the inability to countdown readings, the device allows you to completely stop accounting before the power consumption of several kW.
The device, assembled according to the proposed scheme, is simply inserted into the outlet and the counter begins to count in the opposite direction. All wiring remains intact. Grounding is not necessary. The operation of the device is based on the fact that current meters of electric meters, including electronic ones, contain an input induction converter having a low sensitivity to high frequency currents. This fact allows you to make a significant negative error in the accounting, if the consumption is carried out by high-frequency pulses. These factors allow you to create a simulator generator. The main element of such a device is a capacitor of the appropriate capacity. The capacitor during a quarter of the mains voltage period is contaminated from the network with high frequency pulses. At a certain frequency value (depending on the characteristics of the input converter of the meter), the meter takes into account only a quarter of the actual energy consumed. 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 charge and discharge of the capacitor is the same, but only the second is fully taken into account, creating an imitation of the generator feeding the network. In this case, the counter counts in the opposite direction with a speed proportional to the difference in unit time of the discharge energy and the recorded energy of the charge. The electronic meter will be completely stopped and will allow energy to be consumed without accounting, not more than the value of the discharge energy. If the power of the consumer is greater, then the meter will subtract the power of the device 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: need sufficient knowledge of electronics in the manufacture, and when setting up.
Advantages: all seals and the meter itself remain unchanged, the wiring is also not changed. Grounding is not required. The device turns on in the usual socket, it is possible together with other electrical receivers !!!
Economic effect: With the elements indicated on the diagrams, the device is designed for a nominal voltage of 220 V and a power of 2 мот.
Comment (!): The scheme is fully operational, tested by us in practice.


3. Method "Phase"

Content: for the most energy-consuming electric consumers (electric boilers, electric heaters, electric stoves), an individual electrical outlet is carried out, or, using the above-mentioned electrical appliances, the whole house is connected in such a way that the consumed electricity is not fully taken into account by an electric meter. The method is based on the design features of all (!) Electricity meters. It is carried out within 10-15 minutes without intervention to the internal mechanism of the electric meter, with safety of all seals on the electric meter. To perform slightly change the input scheme (5-10 min.) In some cases and do not (especially in rooms with euro outlets), you need a screwdriver and a piece of cable (1-1.5 m) with a socket. In the executed form there is a possibility of unlimited (!) Electricity consumption either through this outlet or in the whole house, without changing the meter readings.
Pluses:! the easiest to execute! (even a child can perform), suitable for any electricity meters, the possibility of detection is almost impossible since all electrical devices that are not connected to the aforementioned outlet will be counted by an electric meter (the disk will rotate, blink indicators) on our memory from hundreds of intruders, such units are detected, there are no restrictions on the size of consumption and connected electrical devices (only the input conductor cross section). In our top he is one of the first! This is the most popular method among employees of energy supplying organizations, as with electricity consumers !!! :)
Disadvantages: for single phase meters only.
Economic effect: up to 100% of consumed electricity is not taken into account.


4. Method “Zero +”

Content: the method is based on the principle of metering of electricity sold in all (!) (Induction and electronic, single-phase and three-phase) meters. It is performed without intervention to the internal mechanism of the electric meter, with the safety of all the seals on it, only access to it is necessary (the best solution for residents of high-rise buildings). In fact, this solution to the task 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 was difficult to imagine at first. We did not believe for a long time, until we were faced with its implementation in practice.
Now the method is absolutely suitable for all accounting 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 (!) Electricity consumption in the whole house, without changing the meter readings.
Three-phase metering: When executed, 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, ease of execution, suitable for any electric meters, the possibility of detection is excluded, in our memory from hundreds of violators, this one is installed (!), (in truth, after its detection, we completely changed our views on electricity metering and this with experience of about 10 years !!!) there is no limit to the size of consumption and connected electrical appliances (only the cross section of the input conductor). In high-rise buildings performed within an hour. In our top he is the first! The method is virtually unknown to employees of energy supplying organizations !!!
Disadvantages: absent !!!
Economic effect: up to 100% of consumed electricity is not taken into account.


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

Content: when the electric meter “wound” a sufficiently large number of kW / h, its readings can be reduced (rewind). In fact, the method describes the scheme of the device for rotating the dial of the electric meter in the opposite direction, as well as the scheme of its connection. The method is based on the design features of induction meters. It is carried out without intervention to the internal mechanism of the electric meter, with safety of all seals on the electric meter.
Single-phase accounting: to perform slightly change the input scheme (5-10 min.) In some cases and do not, and also make the simplest device - a transformer, with which help reduce readings (twisting of the drums of the counting mechanism in the opposite direction) of the meter. The current flowing through the current coil of the electric meter is approximately 10 Amps, which corresponds to a decrease in its readings by 2.2 units (for the night - 20 kW \ hours, for the month - 600 kW / hours).
Three-phase accounting: Contrary to the popular belief that a three-phase counter cannot be “unwound” in our practice this method was discovered, which we ourselves could not believe, but this is a fact, and he is a scoundrel very stubborn. To implement it, you need access to the input to the electric meter (terminals of the machine or switch (in our detected case, an AP-50 type input was used), or a break in the input cable), they also make a simple device - a transformer, with which help reduce readings (twisting drums counting mechanism in the opposite direction) of the 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 (~ 55 kW \ hours per night, ~ 1600 kW / hours per month).
Pluses: practical choice! after the manufacture of the transformer, the possibility of using almost unlimited number of times. The method of use in the three-phase accounting for many workers of energy supplying organizations is unknown because considered unreal !!! :) )) In our he is one of the first.
Disadvantages: it is necessary to manufacture a transformer, not suitable for electronic electricity meters and electricity meters with a stopper (the ratchet is shown on the panel, and during the rotation of the disk, clicks of the type are heard as the clock ticks, 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. Method “Starter”

Contents: on the input cable, before the electric meter there is a gap (box) from which one end goes to the electric meter, the other to the magnetic starter (rated current depending on the load, usually 25 Amps or more), the starter supplies everything that your heart desires (heating system , electric stoves, saunas, etc.), while providing for the possibility of their connection through an electric meter (in case of verification). The starter’s control circuits (“start” and “stop” buttons) are powered from the network at home, through an electric meter in a convenient place for a quick shutdown (again, in case of testing). There were cases when the buttons were disguised as elements of the interior: pictures, hangers, watches. When checking, the voltage is removed from the load through the starter and the voltage indicator of the verifier does not show anything, the starter itself is carefully masked, and the wiring is placed in the metal hose (a good screen for voltage indicators) and plastered or sewn with clapboard. Often, the load is connected from the gap (box) directly, without the starter, in this case the probability of detection of the “left” wiring by the inspectors increases many times (now all the personnel of the power supply organizations are equipped with voltage indicators, a regular receiver at 50 Hertz, it shows the presence of hidden wiring at a depth of 4 see if it is not shielded).

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


7. Method “Cremation coil voltage”

Content: with the help of the simplest circuit, which is included in a conventional outlet, in three-phase induction meters, the voltage coil of the phase from which the aforementioned outlet is powered fails. The method is quite extreme and requires the presence of mind. watch for an hour at a fuming counter occasionally throwing sparks from a liquid metal (all that remains of a voltage coil) is not enough for everyone! Joke, of course! :) The process of failure of one element of the counter takes a maximum of 2 minutes. This is achieved, as the name implies, by burning one or more voltage coils by applying overvoltage from the above device. All 1000V / 1A diodes, all 50 μF each (as you can see, two of them are connected in series!). Use Conder imported, Soviet explode. WU - this is the rectifier-voltage multiplier, which is included after the meter in one of the sockets of the consumer's network. Its scheme is below the connection diagram of the slave to the meter.


Advantages: the scheme is the simplest, is included in a regular outlet, all seals on the meter and on the input switching device remain unchanged.
Disadvantages: after using this device, one element fails irrevocably i. it is not possible to restore the dead voltage coil without opening the meter.
Economic effect: one-third (with a symmetrical load) or more (if we 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 region, pastas5kv, told us the following, that this method is also suitable for electronic meters (including the most sophisticated ones from ABB (Germany)). The essence of his comment is as follows: with cremation of 2 phases in a three-phase meter, the metering of electricity still goes 100%, since The voltage on the meter controller comes from a single “healthy” phase. If it is turned off, then 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 power supply had disappeared altogether. 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, you only need to turn off two or one “healthy” phases, respectively. И еще один комментарий от pastas5kv: высокое напряжение нельзя подавать сразу на максимум, его необходимо прикладывать несколько раз начиная с небольшого уровня и постепенно увеличивать до тех пор, пока не произойдет пробой изоляции и выход катушки напряжения из строя. Как утверждает автор, если кремацию сделать правильно, то вышедшая из строя катушка внешне практически не отличается от исправной.


8. Способ “Угол наклона”

Содержание: способ основан на конструктивной особенности индукционных электросчетчиков. Выполняется без вмешательства к внутреннему механизму электросчетчика, с сохранностью всех пломб на электросчетчике. Элетросчетчик вместе с щитком на котором он крепится наклоняется относительно земли на угол до 90 градусов (как правило щиток либо на петлях в верхней части, либо крепеж щитка легко вынимается). Когда электросчетчик “лежит на спине”, его диск перестает вращаться не зависимо от подключенной через него нагрузки. Собственно диск перестает вращаться уже при 40-60 градусах наклона
Достоинства: возможность использования практически неограниченного числа раз, простота исполнения, все пломбы и сам электросчетчик остаются без повреждений. Подходит для трехфазного учета. В нашем он один из первых .
Недостатки: не подходит для электронных электросчетчиков, много возни с установкой нужного угла наклона, при внезапной проверке легко обнаруживается.
Экономический эффект: в месяц до 100 % электроэнергии не учитывается.


9. Способ “Измерительные цепи” (включает четыре способа)

Содержание: Если в электросчетчиках непосредственного включения (до 100 Ампер), измерительне цепи встроены внутри корпуса (во многих электронных установлены трансформаторы тока - шинка и обмотка, ничего особенного), то у электросчетчиков рассчитанных на учет электроэнергии крупных потребителей (рабочие токи от 100 Ампер и выше), часть схемы учета установлена вне корпуса электросчетчика - трансформаторы тока и напряжения (для учета в цепях 10 кВ и выше). Существует несколько схем в зависимости от того как организован учет, опломбированы ли цепи измерения, какой вводной коммутационный аппарат, где установлены трансформаторы (на РП, ТП или ЗТП, в ВРУ). В нашей практике были обнаружены сотни схем недоучета электроэнергии, но все они принципиально не отличаются, существуют четыре основных способа, разница лишь в исполнении. 1).Шунтирование вторички трансформаторов тока 2).Изменение полярности трансформаторов тока 3).Отключение проводника катушки напряжения эл.счетчика 4) Шунт трансформатора тока

All manipulations are made at the terminals of current transformers. To do this, you need free access to the transformers themselves, or (if there is) access to the test block (installed before the 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 the one when the whole electricity metering board is sealed, then basically - BURN. 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 (a conventional bracket made of wire with insulation and bare ends for a length that would be enough to touch the secondary contacts). If the CT (current transformers) are not sealed, then the general freebie: by disconnecting the input automat or the breaker (it is impossible under voltage - if the secondary is opened, then a breakdown can occur under the induced potential), unscrew the screws of the secondary wires and insert the same terminal shunt (see above). Reversal of the polarity of the CT is made only on non-sealed secondary terminals. It is done elementary: unscrew the screws securing the wires of the secondary, and they are swapped (wires essno!). Manipulations are carried out at a relieved voltage (see above). The disconnection of the voltage coil conductor is also performed on unsealed TTs. Again, removing the voltage from the TT, 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 to put washers badly conducting currents, they can simply be painted at the point of contact, or it is good to pierce the bare end of the wire (again, worsen the contact!), And install the wire in place. Shunting of the TT itself is also quite simple, disconnecting the introductory automat (knife switch, bag, etc.), with the help of “crocodiles” a conductor of good cross section is fixed (with insulation, essno!) Before the TT and after the TT can be performed in all phases. The method is applicable in some cases when the entire accounting board is sealed. In our top he is one of the first.
Advantages: all seals and the meter itself remain unchanged.
Disadvantages: in any case, basic knowledge of electrical engineering is necessary for a competent collection of the scheme. Constant control over accounting is required, time is needed to parse the scheme (in some cases).
Economic effect: from 30% to 100% of unaccounted electricity consumed (the figure of 100% is true contrary to common sense). In our practice, there were cases with a decent undercounting of electricity, for example: about 30,000 kW / hours per month (flour mill) and 80,000 kW / hours per month (pastry line for the production of cookies), and many others like them. In this case, consumers used this method for more than one month. There are 4 (!) Schemes of its execution.

10. Method “Shock” (includes three methods)

Content: The method is based on the design features of electronic electricity meters. It is carried out without intervention to the internal mechanism of the electric meter, with safety of all seals on the electric meter. There are three ways: 1) for electric meters of the type SET (a case was discovered), it is tightly “wrapped” in black polyethylene and in hot weather after a while it fails, as a rule it starts to “self-propel” with great speed (they say it can stop) , which subsequently establishes a test. 2) for the TsE6807B type meters (with LCD panel), but it is possible for others to do: close the electric meter with an “electric shock” (used for self-defense purposes) and switch on several times until the display on the panel clears. 3) the most extreme: subject to the availability of good wiring (decent section) and automation, include the maximum load (for example, welding) for an electric meter with jerks with small interruptions, as a rule, one or several built-in current transformers fail (secondary) burns.
Disadvantages: suitable only for electronic electricity meters, mostly single use
The economic effect: in each case in different ways, it is difficult to predict.


11. Method “Counter shunt”

Content: the method is rather trivial, its essence consists in the following: from the input switching device to the switching load devices, a so-called shunt is mounted, which is a piece of wire of the required length. In the completed form, when the input device is turned on, most of the consumed electricity is not taken into account, if this device is turned off (and the shunt is connected to the input terminal supply voltage), then all consumed electricity is not taken into account. The easiest way to perform in apartment panels (on the stairwells), because in most cases there is free access to both the input (as a rule, it is a normal bag) and the load (two or more circuit breakers) switching devices. Turning off the input device (turn the bag handle by 90 degrees), check the absence of voltage on the outgoing contacts (with a conventional screwdriver- "probe"), cut the wire (with insulation essno!) Of the required length, strip it from both ends and then fix one end to phase the outgoing contact of the bagger (under the screw, the bare end is formed into a “ring”), the second end of the phase contact of the automatic load cell. That's all ready! Turns on the bag by turning the handle 90 degrees. and the circuit is ready for operation. In the dashboard, the shunt is masked and closed by all switching devices 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 storeyed).
There are even simpler options when the shunt is performed directly in front of the terminal block of the meter, either stripping the insulation of the generator and the load phase wires, and then shorting them (between them directly or using a piece of wire) or by “slipping” under the terminal block cover of the piece counter wires in the form of brackets in the holes between the 1st and 2nd terminals (where the initial generating and load phase wires are mounted).
Disadvantages: if the inspectors once look behind the protective panel hiding the contacts of the bagger and the automata, then the trick is easily detected.
Economic effect: if bypassing only in phase, then the meter underestimates up to 50% of the consumed electricity, if bypassing and zero, then 100% of undercounting is guaranteed.


12. The way “Friends”

Content: the method is applied, as a rule, in cases when one consumer has on his balance sheet 1-f. 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, you must have two meters. The point is this: from one counter the phase is taken, from the other zero. In the case of 1-f. and 3 f. counters, the phase is taken from 1-f., and zero from 3 f. At the same time, before switching the wires, they do not forget to phase (i.e., connect the phase from one meter to the network (socket) of the other meter to the phase contact (find out with a “probe” screwdriver in advance), and zero, respectively). In the scheme 1-f. the counter from which the phase is taken, you need to make changes to the input (change the phase and zero wires in some places) and turn off the zero switching device. In the circuit of the second counter, the phase switching device is switched off.

Disadvantages: we need elementary knowledge of electrical engineering, since it is necessary to make changes in input 1f. meter, mount additional wiring.
Economic effect: up to 100% undercounting of electricity is guaranteed.


13. Voltage screw method (includes two methods)

Contents: with two screws, through the top of which either the fishing line or the wire to which the local energy supplying company establishes its seal is passed through, excluding the consumer’s access to the meter’s terminals. The essence of the method is as follows: the above-mentioned seal is removed, the screw (s) for fastening the cover are unscrewed, and here it is - the terminal. Wow What now? And now the user carefully using a screwdriver with an insulated handle, carefully 1) unscrews the voltage screw (it is easy to detect, it secures a small jumper about 1 cm long on the left side of the terminal block) until the meter disk stops or it stops blinking (if the counter electronic). Yes, by the way, some consumers even 2) replace the two wires from the first and second terminals in places, the effect is impressive - the electric meter dial rotates in the opposite direction, and the electronic one stops (albeit counters began to appear (eg "Solo") 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 you install a washer from a bad electrical conductor (paint it with varnish or graphite grease), prolonged, under the voltage jumper.
Disadvantages: as in the previous method, deformed and fake fillings are very easily determined in 90% of cases.
Economic effect: up to 100% of consumed electricity is not taken into account.


14. Voltage Jumper Method (includes two methods)

Contents: a three-phase electric meter terminal block closes the cover, which is fastened with two screws, through the top of which either a line is passed, or the wire to which the local power supply organization installs its seal, excluding the consumer's access to the power meter terminals. The essence of the method is as follows: the above-mentioned seal is removed, the screw (s) for fastening the cover 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 jumper screws (they are easy to identify, they are installed between the 1st and 2nd, 4th and 5th, 7th and 8th terminals about 1 cm), until the electric meter drive stops or it stops blinking (if the meter is electronic). Yes, by the way, some consumers, when the cover is removed, 2) change two wires from the 1st and 3rd, 4th and 6th, 7th and 9th terminals in some places, the effect is impressive - the meter dial rotates in reverse side, and the electronic stops. Now it's time to put everything in place: the lid, screw (s) and ... the seal, which is carefully threaded through the fishing line or wire, after passing the last one through the screws securing the lid, and then pressing everything with anything (pliers with a cloth on the lips) do not leave traces), fake sealers, etc.).

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


15. Method “Transformer Label”

Content: mainly new consumers are used, the essence is as follows: an existing current transformer, for example, 300/5, is used to install a label (information socket) from a 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 simple to perform, the meter itself does not worry.
Disadvantages: when checking can detect (rarely).
Economic effect: depends on appetite


16. The method of “slot”

Content: Between the glass and the meter housing by pressing or picking out (not to pick up the synonym) glue, a microspace is formed, sufficient to push a strip of thin but durable material (usually film) about 10 cm long and 1 cm wide, until the meter counter touches, which at the same time stops its movement.

Benefits: The effect is instantaneous; it can be used many times, like a coin on a payphone for a pay phone. Suitable for three phase metering.
Disadvantages: upon careful consideration of the glass and the housing of the electric meter, it is very easily detected (the slit itself is visible, and on the glass there are usually scratches and fingerprints (from large traffic :) )). It happened that after disassembling such a counter, the consumer’s natives turned out inside :) )) Only suitable for induction meters (they have something to stop - drive!).
Economic effect: up to 100% of consumed electricity is not taken into account.


17. Method “Hole”

Content: a hole is made at any place of the meter housing (on the right, left, above, below, on the back side (through the wall on which the meter is installed), behind the casing protrusion (rim around the meter’s perimeter 1-2 cm from the back side)) more discreetly, an object such as a needle or needle is inserted into it (preferably from a dielectric material: plastic or wood) of such a size that it reaches the disk of the counter, and as it comes out, the electric meter from the megadivice turns into a piece of carbolite with a filling that even ck does not rotate. There have been cases in history when a hole was found only at the time of delivery of a replaced electric meter to a warehouse (it was made jewelry, the mosquito doesn’t undermine the nose!).

Advantages: electric meter drive does not rotate, so what? That's right, the readings do not change, money is saved (for example, on new boots or a ticket to Penkin in the first row). Suitable for three phase metering.
Disadvantages: not suitable for electronic electricity meters (although some consumers tried to make a hole to stop the stopper of the stepper engine (opposite 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 meter case (although , skin and kuzbass varnish, here they are “crazy hands”).
Economic effect: up to 100% of the consumed electricity is not taken into account by the electric meter.


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

Contents: the meter housing is attached to the base with two or three screws, through the top of which (usually two), either the fishing line or wire (sometimes protected from damage such as Silvire LG9) to which the state verifier (or the manufacturer) is installed is installed by confirming that the device is suitable for operation (works in the class of measurements, 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 far as possible) removed, the screws securing the cover are unscrewed, the cover is removed. Hooray! Do it with a counting mechanism, or with a voltage coil, or with current transformers (for electronic meters), or with an information panel that the soul desires (and she only wants to save paper with watermarks). There are several ways: 1) use a screwdriver to twist the disgusting numbers on the reels of the counting mechanism backwards, 2) solder the voltage coils into the circuit (different from the current coil by an even smaller cross section) resistance or 3) the reed switch (in the future, bringing a permanent magnet to the electric meter, stop), 4) change the information panel to another (for CO-I446 counters, install 10-34 Amperes on the counter (five windows are cut on it), panel from 5-17 Amperes (four windows are cut on it) i.e. instead of units are considered tens of kWh, 5) bite off some of the teeth of the counting mechanism (tens and hundreds, second and third drums), usually through one tooth, etc. 6) solder the shunt into the current coil circuit (especially important for electronic meters, short-circuit current transformers there), 7) tighten the screw of the permanent magnet fixing it closer to the disk (brake the disk), 8) loosen the gear pinion gear with the worm of the disk axis, 9 ) reduce the number of turns of the current coil of the meter. All of this leads ultimately to an underregistration of electricity, but it comes time to assemble the designer: install the casing in place, tighten the screws and oh, mom !!! And with the seals what to do? He shot himself, and primastrychivay. First, the seals are carefully put on the fishing line or wire, then pressed. Yes, I almost forgot, many consumers in a hurry put the meter cover as necessary, but it is necessary to put it as it was - projections up. When pressing a seal, everything goes in the course: pliers with a rag on the lips (so as not to leave traces), sealers, fakes, etc.
Advantages: instant effect (in case of drum twisting with a screwdriver) or prolonged (current coil shunts (current transformers), reed switch and resistance in the voltage coil circuit, replacing the information panel or tapping 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 power supply organizations: be careful, carry a flashlight and magnifier with you!
Economic effect: twisting of the drums of the counting mechanism - up to 100% of the consumed electricity without taking into account, shunt of the current coil - 100% of non-recorded electricity can be achieved, reed switch and resistance - from 30 to 100% of electricity is not taken into account.


nineteen . “DC” method

Content: A significant increase in the negative error of induction el. Meters can be achieved by passing a direct current through their current coils, which will make a magnet out of the core of the current coil. The magnet, in turn, causes the disc to brake. There is a similar (permanent) magnet in each induction el. Counter. Additional magnet - additional braking. In order to simply carry out the supply of direct current through the current coils, two counters connected to the same phase are required. You can, for example, cooperate with a neighbor, or issue an additional counter under any pretext. The secondary winding of the transformer should produce a small voltage of ~ 5 V, such that the current is obtained equal to twice the rated current of the meter. It is selected experimentally. The choke is optional, it allows you to keep a record of electrical energy separately along the circuits, and also smoothes 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 meter stroke by ~ 30%.
Disadvantages: one more phase is needed and it is necessary to make a scheme
Economic effect: up to 100% undercounting of electricity is guaranteed.


20 . “Sprout” method

Contents: for Rostock electric meters SOE-5020N, ​​but also suitable for all on ADE77XX. The meter does not know how to immediately calculate the active power, so it assumes that the total power is equal to the geometric sum of the active and reactive powers. The meter measures total and reactive power, and from these two powers it finds the active one. It is here that the basis of the method is enough to make the counter calculate the reactive power very large and then the counter stops. How to do this - it turns out after 5 readings of the datasheet on the AD7751. For the manufacture of the device, a handful of electronic trash is enough for a total cost of about 4-5 cu.
Disadvantages: need sufficient knowledge of electronics
Economic effect: up to 100% undercounting of electricity is guaranteed.


21. The method of “Heater”

Content: It is no secret that modern household appliances are quite economical, and the payment for the energy consumed by it is not such a heavy stone on the neck of citizens. Another question electric heater (fireplace, sauna, thermal curtain at the entrance to the store, electric boiler, water heater, etc.) - why should I have to pay for heating? And if I'm heating up what I pay for it ??? Absurd! Let's learn how to use an electric heater for free. With the help of our scheme, you can turn on the electric heater in the socket completely unnoticed by the meter. Frankly speaking, you can connect any electrical device that is not demanding to the form of the supply voltage. How does this scheme work? After power is turned on, the mains voltage is supplied simultaneously to the diodes VD1 and the primary winding of the transformer T1. If at the moment the regulator is turned on, the network has a voltage of negative polarity, the load current flows through the emitter-collector circuit VT1. If the polarity of the mains voltage is positive, the 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 oh, how it doesn’t like it. After all, it is known that both electronic meters (they contain an induction current sensor with a magnetic core with limited frequency conductivity) and induction meters (they also contain the mechanical part of the measuring system, apart from the magnetic one) have a very large negative error when the high-frequency current flows. The device is inserted into an ordinary outlet through it and the electrical heating is supplied (fireplace, boiler, etc.), there is no need to access the meter or the input, everything remains unchanged, no grounding is required !!!
Disadvantages: it is necessary to make a scheme that any beginner amateur radio student will really assemble and set up :)
Economic effect: up to 100% undercounting of the electric power consumed by the electric heater is guaranteed.
