ABSTRACT:
A fault current sensor device detects and distinguishes abnormal current events on alternating current overhead and underground power transmission lines. The sensor distinguishes whether the momentary or sustained fault is a line-to-ground fault, line-to-line fault or a three-phase fault. The sensor determines whether the overload has occurred on all three phases, or only on one or two phases, of the power line in an unbalanced situation. The device can be remotely reprogrammed to alter its trigger or threshold level and can be remotely reset after a fault has occurred.
