Picture 1. Earth fault protection of rotor

Earth fault is a common problem that appears when a generator is working and is connected on the system. The insulation of the generator’s rotor coil is working in bad working conditions and is constantly exposed on mechanical and thermal forces, due to the heat dilatation of the rotor coil.

Earth fault can be caused from damaged insulation, filth on the rings and the joint cables. After the first earth fault, it is most likely second fault to occur.
