Zusammenfassung:To provide an inspection device capable of easily performing deterioration diagnosis of PCS in a short time.SOLUTION: An inspection device 2 is a device for inspecting the degradation of aluminum electrolytic capacitor Cdc in an electric power supply control device 6 that has an inverter 62 that converts DC electric power generated by a distributed generator 5 into AC electric power and outputs the same. The inspection device 2 includes: a current measurement unit 22 that measures an output current iac of the inverter 62; a current waveform generation unit 24 that generates a current waveform representing changes over time of the output current iac measured by the current measurement unit 22; and a determination unit 25 that determines the presence or absence of distortion in the current waveform generated by the current waveform generation unit 24.SELECTED DRAWING: Figure 5 【課題】簡単且つ短時間にPCSの劣化診断を行う。【解決手段】検査装置2は、分散形発電機5よって発電した直流電力を交流電力に変換して出力するインバータ62を有する電力供給制御装置6内のアルミ電解コンデンサCdcの劣化を検査するための装置である。検査装置2は、インバータ62の出力電流iacを計測する電流計測部22と、電流計測部22によって計測された出力電流iacの時間的な変化を示す電流波形を生成する電流波形生成部24と、電流波形生成部24によって生成された電流波形の歪の有無を判定する判定部25と、を有することを特徴とする。【選択図】図5
