摘要：PROBLEM TO BE SOLVED: To provide a partial discharge measurement devicethat can improve the accuracy in detection of partial discharge without making aconfiguration of the device complicated and can easily determine a phase where partialdischarge occurs.SOLUTION: A surface current sensor 11 provided on an exterior surfaceof a metal shield instrument 12 detects a current excited by partial discharge inside themetal shield instrument 12; a voltage detection device 15 detects a voltage to be appliedto the metal shield device 12; a display device 16 synchronizes a waveform of the currentdetected by the surface current sensor 11 and a waveform of the voltage detected bythe voltage detection device 15 and displays on the same temporal axis.SELECTEDDRAWING: Figure 1
