Abstract

Grounding of electrical installation is primarily concerned to ensure safety. The main purpose of grounding is to channel the fault current straightly to earth during fault condition. In order to create a good grounding system, the value of ground resistance must be reduced as low as possible. Otherwise, current may flow through to personal or damage electrical equipment instead of flowing through grounding system. The aim for this project is to study coconut husk efficiency as additive material for soil treatment in order to improve soil resistivity. Besides that, the galvanized steel rod electrode is investigated as alternative to copper steel rod to reduce the theft activity. In order to determine the good grounding, the experiment has been conducted on 6 different type of installation which is copper steel rod electrode, galvanized steel rod electrode without added with coconut husk and galvanized steel rod electrode added with coconut husk in different type of installation. The different type of installation is by added coconut husk with different weight which is 1kg, 1.5kg, 2kg and added coconut husk layer-by-layer with local soil. The treatments are done to enhance the performance of the galvanized steel rod in grounding system compared with copper rod. It shown grounding system performance such as grounding resistance gives better result compared to the conventional rod. Furthermore, the soil resistivity was reduced due to the ability of coconut husk that store water. Thus, it will lead improvement of grounding system.
