§ 18 So how do you still unwind or stop the electronic counter

Electronic counters do not rewind. He has a 4-quadrant measurement, he simply measures the countercurrent and puts it in another drive different from the direct one. That is, it measures active and reactive energy in both directions, keeps a record of events, and all that can be imagined. And if one moment he fixes that your apartment suddenly began to give energy to the network, then the audit organization will have all the occasions to fuck you repeatedly, and printing a report will be proof of that.
Designers of counters also provided such simple forts as the blocking of the current coil (the counter records the time when no power was consumed). That is, if it turns out that at 9:00 in the winter you have not burned a light bulb for a month, then this is a serious reason for the visit of inspectors to visit.
There is protection and from especially clever - the counter fixes time of failures of the processor and its restart.
