To provide an abnormality diagnostic device of a power plant which can be easily attached/detached and accurately diagnose the presence/absence of occurrence of an abnormality in a power plant in a short measurement time and an abnormality diagnostic method using the abnormality diagnostic device.SOLUTION: An abnormality diagnostic device diagnoses an abnormality in a power plant which includes a housing and a conductor that is fixed to the housing at a prescribed fixation spot and supplies a current to a load. The abnormality diagnostic device includes an excitation unit and a measurement unit. The excitation unit applies vibration to the conductor. The measurement unit measures a value indicating the characteristics of the vibration applied to the conductor by the excitation unit. The excitation unit and the measurement unit are arranged at the fixation spot or in the vicinity of the fixation spot.SELECTED DRAWING: Figure 2 【課題】着脱が容易で短い計測時間で電源設備における異常の発生有無を精度よく診断可能な電源設備の異常診断装置、および該異常診断装置を用いた異常診断方法を提供する。【解決手段】異常診断装置は、筐体と、筐体に所定の固定箇所で固定されて電流を負荷に供給する導体とを備えた電源設備の異常を診断する。異常診断装置は、加振部と計測部とを備える。加振部は、導体に振動を与える。計測部は、加振部が導体に与えた振動の特性を示す値を計測する。加振部および計測部は、固定箇所もしくは当該固定箇所の近傍に配置される。【選択図】 図２
