Abstract :
An optoelectronic sensor for real time leakage current monitoring on high-voltage (13.8 kV) power line insulators was developed. The leakage current drives an ultra-bright green LED producing an AM light signal. The optically intensity-encoded signal is coupled to a 1-mm plastic optical fiber and transmitted from the high potential measurement point to the Remote Unit in ground potential. After the demodulation, the leakage current values are concentrated in a data logger and sent to a remote station 150 km away by GPRS technology.
