摘要：PROBLEM TO BE SOLVED: To provide a partial discharge diagnostic apparatuscapable of obtaining a minute partial discharge signal by increasing the sensitivity of asurface current sensor and further improving the performance. A partial dischargemeasuring device (measuring device 100) according to the present invention comprises asurface current sensor 11 which is installed on an exterior surface of a metal shieldingdevice and detects a current excited by a partial discharge in the metal shielding device. ,The voltage detection device 15 that detects the voltage applied to the metal shieldingdevice, the current waveform detected by the surface current sensor 11 and the voltagewaveform detected by the voltage detection device are synchronized and displayed onthe same time axis. A surface current sensor 11 including a display device 16 ischaracterized by including a conductor 31 in which a plurality of flat antennas are
laminated. [Selection diagram] Fig. 3
