Title:
PARTIAL DISCHARGE DETECTION DEVICE AND PARTIAL DISCHARGE MONITORING SYSTEM
Document Type and Number:
Japanese Patent JP2021025881
Kind Code:
A
Abstract:
To provide a partial discharge detection device and a partial discharge monitoring system for permitting continuous monitoring of a partial discharge generated in an electrically insulated material provided in electric facilities by a simple configuration.SOLUTION: A partial discharge detection device for detecting a partial discharge generated in an electrically insulated material provided in electric facilities by a change in ground voltages of the electric facilities caused by the partial discharge includes a sensor for measuring ground voltages of the electric facilities, and an analog electronic circuit for lowering frequency of waveform signals of the ground voltages measured by the sensor and outputting the signals. The analog electronic circuit is configured by using an electron element having predetermined capacitance.SELECTED DRAWING: Figure 4
