Abstract

A partial discharge measuring method is carried out by providing a closed circuit for measuring outside of an object to be measured, the closed circuit for measuring comprising a capacitor in which an impedance for a frequency band of a partial discharge is smaller than an impedance for a commercial frequency, and detecting a partial discharge current flown through the closed circuit for measuring by a high frequency transformer.
