Comparison of Electromagnetic Wave, Light Intensity and Electric Charge of PD on Crossed Magnet Wires under Repetitive Impulses

Abstract

For PD detection of converter-fed motor windings, electromagnetic wave is one of the promising signals because of remote detection. This paper described fundamental relations of electromagnetic wave and other optical and electric signals from PD using crossed magnetic wires under repetitive impulses. Detection capability of plural PD pulses under one voltage impulse is discussed in detail.
