ABSTRACT:
A method and a fault sensor device (1) which can detect and distinguish abnormal current and voltage events on an alternating current overhead and underground transmission line or distribution line (2). The fault sensor device (1) is contained in an elongated molded plastic housing (4), The fault sensor device (1) includes a current sensor (12) and a voltage sensor (14) connected in proximity to the transmission or distribution line (2) for monitoring current and voltage analog signals; an analog-to-digital converter (22) connected to the current and voltage sensors (12,14) for sampling the current and voltage analog signals and producing: corresponding digital signals; a processor (11) responsive to the digital signals for detecting an abnormal condition and distinguishing whether any of a plurality of types of faults has occurred; and a transmitter (3) for transmitting the fault information from the processor (11) to a remote location.
