Contamination Level on Insulators of Cambodia High Voltage Transmission line

Abstract

Insulator is an important component in the operation of power system because it might cause flashovers and so excessive outages under awful weather condition. Under the environment along with weather condition produces flashover on contaminated insulators as a result to interrupt in a power system. Accordingly, determining pollution severity is an important facet of the procedure behind improved insulator selection, installation, and maintenance. The contamination level has been carried out by an equivalent salt deposition density (ESDD) experiment. The collected data from the site measurements were used to investigate the contamination level. This study has used multiple regression to build ESDD with different weather condition variables such like rainfall, temperature, pressure, humidity as well as wind speed for predicting contamination levels on high voltage insulator surfaces. The multiple regression predicted values have been compared with the measurement values. The results are effective to reveal the contamination level that occurred on the insulator surface high voltage insulator in Cambodia.
