Abstract

Taking the way of artificially simulating defects

where a discharge model is placed into GIS device

the time delay calculation methods in the time difference based localization technology for partial discharge source in GIS are researched experimentally. The time delay calculation methods include the signal waveform characteristic point method and the LMS based adaptive time delay calculation method. Experimental results show that the LMS based adaptive time delay calculation method is more satisfactory with higher accuracy.
