Abstract

Maintaining high reliability in power networks is very important hence condition assessment of naturally aged polymeric insulators was aiming to get a better understanding towards the involved aging process. This project introduces the condition monitoring of field-aged high voltage polymeric housing insulator by making comparison of degradation between shed of 12 years insulator using the hydrophobicity properties and leakage current (LC) signal parameters. The purpose of this project is to investigate the status of hydrophobicity on the surface of the insulator. The input signal parameter used spectrogram to extract electrical signal parameter using MATLAB software and the data obtained would only focusing on mechanical and electrical part that used spectrogram to extract signal parameter such as 2-dimensional mean. Due to some factors and harsh environmental conditions that accelerate the process of aging, the performance and degradation of polymeric insulators was able to be evaluated by testing and comparing their sheds.
