Abstract

This paper have investigated the possibility of the insulation defect location of a stator by detection of electromagnetic wave. Sinusoidal voltage with 50Hz is applied between the stator and stator cores. And, the maximum antenna load voltage has been measured. The results which have been confirmed are: (1) the electrical discharge of location of insulation defect can be estimated in the applied voltage of PDIV. Detection of electrical discharge location is possible in applied voltage higher than PDIV by exploiting frequency of detected voltage. (2) the detection accuracy of the insulation defect location depends on polarization of a shielded loop antenna.
