Abstract

See full text

A sensor apparatus for detecting leakage current in a post-type insulator of an electrical power system includes: a sensor unit having a housing, the sensor unit including: a sensor assembly operable to generate an analog signal proportional to a received leakage current; an electronics module operable to covert the analog signal to a digital value; and a communications system operable to wirelessly transmit the digital value to an external receiver; a collection band adapted to be connected to an exterior surface of the insulator; and a transfer lead interconnecting the sensor assembly and the collection band, the transfer lead operable to transfer leakage current from the insulator from the collection band to the sensor assembly.
