Earth fault compensation unit

This earth fault compensation unit is connected between the neutral line and the earth to compensate the capacitive earth-fault current by selecting the correct inductance. The unit can be adjusted to variable settings in order to facilitate matching of the earth-fault inductors to the various switching states of the power supply system. (Petersen coil)
