On-site Combination of Withstand Voltage Testing and Partial Discharge Measurement for XLPE Power Cable Accessories

Power cables are of great important in power transmission and distribution systems. Power cable system basically consists of cables themselves and their accessories. Cable accessoires consist of joint and termination. Joint is special connection component which used to join two cables ends together while termination is special component to provide the end of a cable. Partial discharge (PD) measurements are most important and preferred to study and they have received much attention in recent years. Identification with certain PD patterns and localization of PD are most important aspects. Tell now for the after installation test, PD measurements are actually not required by IEC 60840 and IEC 62067, but the testing experience shows a population of exteude cable system subjected to a…
