摘要：
A ground fault detector which exhibits greater sensitivity to sensing coil current during the initial portions of a-c line voltage half-cycles than during the final portions of those half cycles. This improves its response to resistive ground faults in the presence of unbalanced capacitance to ground conditions of the a-c power lines.
