What happens when the neutral and ground wires are reversed?
Apr , 12 2024
AC power is basically generated by the generator in the power plant. The generator has three-phase windings with an electrical angle difference of 120 ° between them. When connected in a star connection method, there is a common point between the three windings, called the neutral point. This neutral point N is usually connected to the ground PE, so it is called PEN together. If the output current...
