UHF anti-interference positioning and optimal layout method of oil-paper insulation defect partial discharge

UHF anti-interference positioning and optimal layout method of oil-paper insulation defect partial discharge

Ultra high frequency (UHF) partial discharge (PD) detection is a common method for transformer oil-paper insulation defect location. However, the accuracy of PD positioning in practical application is easily affected by noise and sensor layout. In order to ensure the effectiveness of PD positioning...
