To provide a connection diagnostic system which detects an electric current between a switch gear and a power supply device, and controls erroneous judgement while performing connection diagnosis of the switch gear.SOLUTION: A connection diagnostic system 10 is a connection diagnostic system 10 for a switch gear 19 connected between a power generator 13 and a power supply device 18, and comprises: a current sensor 22 which detects at least one electric current between the power generator 13 and the switch gear 19, and between the switch gear 19 and the power supply device 18; a voltage sensor which detects a voltage of the power supply device 18 or an input/output voltage of the connection diagnostic system 10; and a diagnostic device 24 which performs connection diagnosis of the switch gear 19 on the basis of electric current detected by the current sensor 22. During a required voltage for the power generator 13 is a voltage substantially sams as the voltage detected by the voltage sensor, the diagnostic device 24 stops connection diagnosis of the switch gear 19 based on electric current.SELECTED DRAWING: Figure 1
【課題】スイッチ装置と電源装置との間の電流を検知して、スイッチ装置の接続診断を行いつつ、誤判定を抑制する接続診断装置および接続診断方法を提供する。【解決手段】本発明の一実施形態に係る接続診断装置10は、発電装置13と電源装置18との間に接続されたスイッチ装置19の接続診断装置10であって、発電装置13とスイッチ装置19との間、または、スイッチ装置19と電源装置18との間の少なくとも一方の電流を検出する電流センサ22と、電源装置18の電圧または接続診断装置10の入出力電圧を検出する電圧センサと、電流センサ22が検出した電流に基づきスイッチ装置19の接続診断を行う診断装置24と、を備え、発電装置13への要求電圧が、電圧センサが検出した電圧と実質的に同一の電圧である間、診断装置24は、電流に基づくスイッチ装置19の接続診断を停止する。【選択図】図1
