PARTIAL DISCHARGE DETECTING METHOD AND DETECTING DEVICE OF GAS INSULATING DEVICE

摘要

PROBLEM TO BE SOLVED: To enable a reliable identification of a generation of partial discharges even when electric noise pulses are outputted from a photoeletric transducer. ;SOLUTION: When lightwave pulses are not generated, the average No of the number of pulses per unit time of electric noise pulses outputted from a photoelectric transducer 6 is obtained in advance. When measuring partial discharge, the average Nm of the number of pulses per unit time of electric pulse outputted from the photoelectric transducer 6. The generation of partial discharges is identified and informed when the average Nm is larger than the above-mentioned average No.;COPYRIGHT: (C)1997,JPO
