Development of partial discharge test device based on pulsic polarity discrimination method

Demin Tu

Abstract

Based on pulsic polarity discrimination method,the partial discharge test device with strong anti-interference capability was designed and realized.According to the difference of the polarity between the sample partial discharge in the balancing circuit and the external discharge,through the logical judge the internal partial discharge can be tested in an environment with severe electromagnetic interference.The amount and the pattern of discharge can be reflected and viewed directly.
