Abstract

This paper describes the prediction of location of PD signals in GIS using the difference in the measured time between first and second wave arrival by the external-type PD sensors. It is well accepted that the electromagnetic wave in GIS propagates at the velocity of $3{\times}10^8$m/s. Consequently, we could identify the location of PD with high accuracy. The experience at the fields and the problems for the judgment are also discussed in detail.
