Summary:To provide a partial discharge detection device that detects partial discharge in a rotary motor without adding a sensor for detecting partial discharge.SOLUTION: A partial discharge detection device 10 for a rotary motor 1 including a thermistor 2 extracts a high frequency component corresponding to a partial discharge from a voltage output generated by the thermistor 2 included in the rotary motor 1 and detects a partial discharge occurring within the rotary motor 1 based on the high frequency component.SELECTED DRAWING: Figure 1 【課題】部分放電を検出するセンサを追加することなく回転電動機の部分放電を検出する部分放電検出装置を提供する。【解決手段】回転電動機１の部分放電検出装置１０であって、回転電動機１は、温度検出用のサーミスタ２を備え、サーミスタ２が出力する電圧から部分放電に対応する高周波成分を抽出し、当該高周波成分に基づいて回転電動機１において発生した部分放電を検出する。【選択図】図１
