“…They typically happen inside cavities, cracks, or any foreign material present in a solid insulator, or bubbles in the liquid dielectric as noted in references [11,12]. Manufacturing defects [36], surface contamination [38], operating environment such as temperature and humidity [28,29] and ageing of material [15,37] can initiate PD event and the type of applied voltage and the insulation medium [29][30][31][32][33]. The theory of PD occurrence is essentially identical for all PD types, therefore the below mentioned categorization is simply a way of organizing it based on discharge location and the various forms it takes.…”

Power cables are one of the equipment that plays a vital role in the power system network, either in High Voltage (HV) or Medium Voltage (MV) network. To ensure a reliable power supply and distribution, the integrity and the condition of the cable system must be ensured. Partial Discharge (PD) diagnosis is a valuable tool to analyse and evaluate the condition of the insulation. The purpose of this paper is to review how PD activity is being utilized to assess the condition of the XLPE (cross-linked polyethylene) cables specifically in MV level where a review of existing PD test methodology that are used by researchers and engineers to diagnose the insulation condition of the cable will be presented.
