Rotary electric machine managing system

A rotary electric machine managing system which manages breakdown voltage-related information related to a breakdown voltage of an insulating member, for a rotary electric machine that has a rotor and a stator in which a stator coil is housed in a stator slot formed in a stator core via the insulating member, the rotary electric machine managing system including:

• an image data generating unit configured in such a way as to generate image data which indicates past breakdown voltage-related information related to the breakdown voltage of the past, present breakdown voltage-related information related to the breakdown voltage of the present, and future breakdown voltage-related information related to the breakdown voltage of the future as the breakdown voltage-related information, wherein
• the past breakdown voltage-related information is information found based on a partial discharge signal obtained from the rotary electric machine at a time of operation in the rotary electric machine of the past, and
• the present breakdown voltage-related information is information found based on a partial discharge signal obtained from the rotary electric machine at a time of operation in the rotary electric machine of the present.
