In the distribution transformer;
In the transformer used for the distribution of electricity to the houses, 3.3 kilovolts enters and 400 volts come out. When we make the phase-neutral calculation, that is, when we divide it by √3, we get 230 volts and 220 volts coming to the sockets. Where does the remaining 10 volts go? (Can you explain with figure)
