Abstract Electrical tracking develops from surface discharge activity associated with the flow of leakage current on insulator surface under wet and contaminated conditions. Arcs created from this surface discharge phenomenon burn the polymer insulator material and create carbonized tracks in the long run. This paper reports on electrical tracking performance through the observation of leakage current of linear low-density polyethylene and high density polyethylen. An electrical tracking and erosion test using the inclined-plane tracking method ( IEC 587) is conducted to study the overall performance of surface tracking properties.

In the present work, electrical tracking performance has been studied with linear low-density polyethylene (LLDPE) and high-density polyethylene (HDPE) materials under AC voltage with amonium chloride ( NH4Cl ) as the contaminant.

The experimental results show that different material can make the different of leakage current rating . The experimental also show the affect of leakage current on Low Linear Density Polyethylene and High Density Polyethylene ( as a polimer material) electrical tracking process.
