Abstract

High voltage insulation breakdown has been the main cause of high voltage systems for a long time. It is found that this phenomenon occurs due to the existence of partial discharge within voids found in the insulation of XLPE cables, which produced accidentally during the extrusion process of cables. The effect of partial discharge would lead to serious breakdown and electrical apparatus failure. Many appropriate techniques can be used to evaluate the condition of XLPE cables. One of the techniques is partial discharge testing. This study focuses on 11 kV XLPE cables and the partial discharge testing is performing using partial discharge detector, TE 571. The analysis of data shows that the partial discharge test can be used to evaluate the performance and behaviour of the XLPE cable. And if the PD value is more than 10 pC, the XLPE cable should be assumed as fail and not safe to be used anymore.
