Abstract
A circuit interrupter including a line conductor, a neutral conductor, a power supply, a ground fault current transformer structured to sense a ground fault current from current flowing through the line and neutral conductors, a grounded neutral detection circuit including a filtering stage structured to high-pass filter the ground fault current, and a processor structured to receive an output of the grounded neutral detection circuit and to determine whether a grounded neutral is present based on the output of the grounded neutral detection circuit.
