Title: Insulation monitoring device for electric apparatus
Inventor: SAITO MUNECHIKA
IPC: G01R31/00
Filed: 1996-04-26
Abstract: PROBLEM TO BE SOLVED: To provide an insulation monitoring device without an error in judgment when partial discharge from an electric apparatus is detected by an antenna. SOLUTION: In an insulation monitoring device, signals at a plurality of frequencies is taken out of detection signals of a partial discharge antenna 3 and a noise antenna 4 using a tuning amplifier 7. Noises are removed from the signal (a) of the partial discharge antenna 3 using the detected signal (b) from the noise antenna 4 to judge whether the partial discharge is generated or not. When signal level of the noise detection antenna 4 is above a given level, the partial discharge in judgment is canceled by estimating an influence of oscillation of an amplifier. At a point, where noise generation is judged, the signal of the partial discharge is replaced by a small level signal to obtain a signal (c). Then, the judgment whether partial discharge is generated or not is carried out on the basis of the signal (c).
