As a non-destructive local gas breakdown phenomenon within a surface or bulk cavity
surrounded by insulation, partial discharge (PD) contains important information which can …

Partial discharge (PD) activities are the essential contributor of insulation failure, which
constitute more than 60% for damaging high voltage equipment. This article presents a …

Transient superimposed voltage, which is accompanied by a temperature gradient caused
by Joule heat, can threaten the insulation safety of high-voltage direct current (HVDC) cable …

Electrical tree growth is a well-documented process leading to failure of high voltage
polymeric insulation under AC stresses. However, tree growth in HVDC insulation failure is …

Electrical treeing is a main cause of long term degradation of polymeric insulation and
inorganic nanofillers have been added to improve the treeing resistance of polymers. In this …

To improve the safety and efficiency performance of partial discharge detection in a high-
voltage direct current (HVDC) cable system, an optical fiber ultrasonic detection system for …
