Statistical lightning study for 33kV overhead line in peninsular Malaysia

Abstract

This paper presents a statistical lightning study for 33kV overhead distribution line located in Northern area of Peninsular Malaysia during a period from 2008 to 2018. Data was collected by Lightning Detection System Network operated by TNB Research Sdn Bhd. The ground flash density and mean peak current maps of the selected line is produced. In addition, a cumulative probability distribution curve is obtained and compared to the widely used CIGRE curve. These few statistical parameters are useful in for several other applications, especially in determining the correct rating for arrester and in evaluating the performance of the line. © 2019 IEEE.
