The idea of getting free electricity is using the potential difference between the network zero and the ground.
A small caveat: this way of generating energy works 100 percent. This is not a hoax, no device that is not clear and draws electricity from the ether, no miracle device with magnets, etc.
We will use the voltage difference between the zero of the 220 V network and ground.
In simple terms, wires go from the power plant to consumers - zero and three phases. Since the wires have their own resistance, therefore, they will also have a "sag" voltage. This is the tension we will catch. This potential also creates a phase imbalance.
It is legal?
Yes, the power grid is not punished for this, since we will not use the phase. And in fact, this is not theft.
Will electric meters take this energy into account?
It all depends on the type of meter. There are counters with one shunt (with one measuring element) - the most common and two shunt (with two measuring elements). One shunt just does not take into account zero - since the measuring shunt in them is located in phase.
How much electricity can I get?
It all depends on the number of subscribers in the network and the power of the entire wiring. Usually it is somewhere around 3-10 volts. If you connect a step-up transformer, you can light up the LED lamp. The voltage after the step-up transformer is about 100-220 V.
Scheme
Any transformer from a radio, tape recorder, etc. It is desirable for a low voltage of 3-9 volts of the secondary winding.
Note that you use all the manipulations at your own peril and risk.
Precautionary measures
Be sure to put a fuse or an ampere circuit breaker of 5-10 in the circuit between zero and the transformer. This is necessary so that the entire structure does not burn out if you suddenly change the phase with zero. The probability of this event is certainly negligible, but you need to be prepared for everything. Rather, it is more likely that zero will break - and this happens all the time. And the machine will definitely save you.
Even when working with zero, be sure to disconnect the network. Well, even free light should not be left unattended.
