Abstract
A partial discharge measurement system including at least one sensor configured to detect a voltage signal propagating through a conductor connected to a rotating electrical machine in a non-contact manner, a first bandpass filter configured to pass a component of a first frequency included in the voltage signal therethrough, a second bandpass filter configured to pass a component of a second frequency included in the voltage signal therethrough, the second frequency being lower than the first frequency, a phase acquirer configured to acquire a phase waveform of the component of the second frequency having passed through the second bandpass filter, and an output interface configured to output information by which a component of partial discharge of the rotating electrical machine included in the component of the first frequency having passed through the first bandpass filter can be identified based on the phase waveform.
