摘要
A partial discharge detection apparatus detects a plurality of discharge events, finds a time interval between the plurality of discharge events, and determines, where the discharge events occur at a time interval shorter than a threshold time, that a partial discharge has occurred within a metal enclosure, or determines, where the discharge events occur only at a time interval longer than the threshold time, that a discharge has occurred outside the metal enclosure. The partial discharge detection apparatus can thus readily distinguish between a partial discharge that occurs within the metal enclosure of a gas-insulated switchgear and a discharge that occurs outside the metal enclosure.
