A generator control circuit is provided that includes a first circuit (44) monitoring a generator voltage change rate and producing a first output when the voltage change rate is above a first level, a second circuit (48) monitoring a generator current change rate and producing a second output when the current change rate is above a second level, and a third circuit (13, 28) operatively connected to the first circuit (44) and the second circuit (48) for decreasing a power level supplied to the generator when a plurality of conditions are satisfied, the plurality of conditions including the voltage change rate being above the first level and the current change rate being above the second level. A method of controlling a generator is also disclosed.
