CAPACITANCE REJECTING GROUND FAULT PROTECTING APPARATUS AND METHOD |
摘要 |
A method of controlling a load in response to a ground fault condition includes measuring a ground fault alternating current flowing from the load. A real part and an imaginary part of the ground fault alternating current is ascertained. Electrical power is removed from the load and/or the ground fault condition is indicated to a user if a magnitude of the real part exceeds a first predetermined threshold and/or a magnitude of the imaginary part exceeds a second predetermined threshold.
