Classification: CPC H | IPC H

Claim 9:
10. A system, comprising:
a first voltage sensor configured to monitor a point of regulation voltage;
a second voltage sensor configured to monitor a generator output voltage of a generator;
a generator excitation field relay electrically coupled between a generator excitation field of the generator and a power source of the generator excitation field, wherein the generator excitation field relay is controllable to open when the first voltage sensor detects an overvoltage condition from the point of regulation voltage, the second voltage sensor detects an overvoltage condition from the generator output voltage, or a third voltage sensor detects an overvoltage of an input signal to the generator excitation field that induces the generator output voltage to an overvoltage fault value;
a deenergizing circuit, comprising:
a logic gate configured to receive one or more fault indication signals from the first voltage sensor, the second voltage sensor, or both; and
a first solid-state switch configured to open when the logic gate receives at least one of the one or more fault indication signals, wherein opening the first solid-state switch results in deenergizing the generator excitation field.
