Free electricity for lighting
The idea of obtaining free electricity is using the potential difference between the network zero and the ground.
A small disclaimer: this method of generating energy works 100 percent. This is not a hoax, some incomprehensible device that draws electricity from the ether, some kind of miracle device on magnets, etc.
We will use the voltage difference between the 220 V network zero and ground.
In simple terms, there are wires from the power plant to consumers - zero and three phases. Since the wires have their own resistance, therefore, there will be a voltage drop on them. 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 electricity meter. There are meters with one shunt (with one measuring element) - the most common and two-shunt (with two measuring elements).One shunt I just don’t take into account zero - since their measuring shunt is located on the phase.
How much electricity can you get?
It all depends on the number of subscribers in the network and the power of all wiring. Usually it's somewhere between 3-10 volts. If you connect a step-up transformer, you can light an 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 advisable to use a low voltage of 3-9 Volts on the secondary winding.
Please note that you use all manipulations at your own peril and risk.
Precautionary measures
Be sure to install a 5-10 ampere fuse or circuit breaker in the circuit between zero and the transformer. This is necessary so that the entire structure does not burn out if the phase with zero is suddenly changed. The probability of this event is, of course, negligible, but you need to be prepared for anything. Rather, there is a high probability that the zero will break - and this happens all the time. And the machine gun will definitely save you.
Even when working with zero, be sure to turn off the network. Well, even free light should not be left unattended.
