description An abnormality detecting apparatus in which noise is rejected in determining the condition of each of rotating electrical machines, so that a partial discharge of a rotating electric machine is detected with high accuracy. The abnormality detecting apparatus includes partial discharge detectors for detecting a partial discharge of a rotating electrical machine, a switching unit for selecting a partial discharge detector, a partial discharge measurement section for measuring the signal from the selected switch, a computer for selecting the respective partial discharge detectors or sequentially selecting respective partial discharge detectors for measurement, noise rejection, insulation diagnosis judgement, and data management for the respective discharge detectors, and for displaying measurement results, and a control section for controlling the switching unit and the partial discharge measurement section through the computer.
