ABSTRACT:
A leakage current detecting coil is provided in the output circuit of the armature of a generator. The output of the leakage current detecting coil is connected to a gate control circuit for a pair of thyristors constituting a full-wave rectifier circuit provided between the output of the generator and the field coil thereof. The full-wave rectifier circuit controls the exciting current of the generator and also interrupts the exciting current through turning-off the thyristors when the leakage current is detected.
