Abstract

PURPOSE:To efficiently remove external noise and to perform measurement based on the voltage waveform of a main circuit by simple constitution, by controlling a corona detection sensor on the basis of the commercial frequency voltage of the main circuit detected from a corona detection terminal. CONSTITUTION:A receiver 30 generates a sensor controlling pulse on the basis of the voltage waveform of a main circuit from a main circuit voltage detection sensor 20 to send the same to corona detection sensors 10a, 10b. The corona signal from a corona detection terminal 5 is sent to a gate circuit 13 through a filter circuit 11 and a detecting and amplifying circuit 12. The light pulse sent from the receiver 30 is photoelectrically converted by an O/E converter 17 to control the gate circuit 13. The corona signal passed through the gate circuit 13 is converted to a light signal by an E/O converter 15 through an A/D converter 14 and transmitted to the receiver 30 through an optical fiber 40.
