Problem solving of partial discharge on the distribution system

This paper presents the mitigation methods of PD on PIC in Provincial Electricity Authority (PEA) distribution system. The area located near the coast will be selected as the pilot project because of having strong occurrence of PD which is mainly caused by salt contamination. The methods applied in this experiment consist of using tie wires made from an insulation sheath of low voltage cable, the sheath of PIC itself; composite tie wire and aluminium tie wire (reverse loop binding). Following the trial results, there are two methods that considered as the most effective ways for PD solving; binding PIC by using the PIC's insulation sheath and the composite tie wire instead of aluminium tie wire (conventional binding).
