Abstract
The high voltage outdoor insulator is an important component in ensuring the safe and reliable operation of transmission system to deliver uninterrupted electric
power to the consumers. However, due to its widespread application through the globe, sometimes it may experience some serious damage due to various environment factor which include pollution flashover. In this particular event the insulator often sustain severe dry band arcs and surface tracking on its surface, leaving a carbonized conductive path on its surface which might induce another pollution flashover event. Generally, through the course of history, there were several types of outdoor insulator available in the market which include porcelain, glass as well as polymer insulator. However, porcelain and glass insulator was known to sustain the most damage once dry band arcings occur on its surface, leading to diversion of researcher’s attention towards the advantage offers by polymer insulator including light weight, hydrophobic and low cost. Although it offers many advantage to sustain various environmental stresses, polymer insulator still need some improvement especially when it comes to its tracking performance thus leading to several past researches was done to use filler in the insulator. This researchers only focuses on the effects or tracking performance of the insulator without any clarification done to prove the factor which causes it to occur. Thus this knowledge gap was exploited in this project by simulating the IPT standardized in IEC 60587 standards. The dry band lengths and angle of applied voltage were varied to further observe its effect towards electric field distribution along the simulation model. The nominal voltage used was 4.5 kVrms as its angle was varied with 45 degree difference.
