ABSTRACT:
An overvoltage protection circuit utilizes the fault current sensing capabilities of a differential protection circuit in combination with a shunting circuit to protect a power generating system against an overvoltage condition. The circuit offers the combined advantage of protecting attached load equipment from the harmful effects of an overvoltage condition while also ensuring rapid deexcitation of a generator.
