Abstract :
It was reported previously that partial discharge (PD) existing in GIS can be localized with a PD localization method based on the time difference of PD detection, in which more than one pulse current sensors are installed at the GIS sealing end or cable termination. However, the localization accuracy is not satisfactory since the PD propagation speed is too high and not average inside GIS. To increase the accuracy combined PD sensors to detect pulse current and to catch the acoustic signal were applied for the on-site PD localization. The result shows that higher location accuracy can be obtained.
