METHOD FOR DETECTING ELECTRICAL FAULTS IN A CIRCUIT
First Claim
Patent Images
1. A method for detecting electrical faults in an electrical circuit having transmission wires for power transmission, the method comprising:
- a first sensing of at least one of a voltage or a current along at least one of the transmission wires;
determining a potential electrical fault condition based on the sensed at least one of the voltage and current;
reducing the power transmission along the at least one of the transmission wires below a first predetermined threshold;
a second sensing of at least one of a voltage or a current along the at least one of the transmission wires;
comparing the sensed at least one of the voltage or current against a corresponding voltage or current threshold; and
determining an electrical fault has occurred when a characteristic of the second sensed at least one of voltage or current satisfies a corresponding voltage or current threshold.

Abstract
A method for detecting electrical faults in an electrical circuit having transmission wires for power transmission includes determining whether a potential electrical fault condition exists along the transmission wires and confirming the potential electrical fault is an actual electrical fault. If the potential electrical fault is confirmed as an actual electrical fault, the method may disable the electrical circuit.
