Comparative study between structure bonding method and conventional method for lightning protection system

Abstract

This paper presents the comparative study between structure bonding method and conventional method for lightning protection system (LPS). LPS is utilized to prevent any harm to the structure due to lightning strike. There are two types of LPS methods which are currently being used by the Malaysian Public Works Department (also known as Jabatan Kerja Raya or JKR). The methods are structure bonding method and conventional method. Both LPS methods must have earth electrode resistance less than 10Ω. In order to evaluate the methods, measurements of the earth electrode resistance using Digital Earth Tester Kyoritsu Model 4105A are conducted. It is found that the average earth electrode resistance for conventional method is 4.29Ω while the average earth electrode resistance for structure bonding method is 1.76Ω. Based on the average earth electrode resistance, we found that structure bonding method has a lower earth electrode resistance compared to the conventional method.
