Comparative study of tyre ash and palm kernel oil cake as back-filling agents for effective grounding

Abstract

A simple method for analyzing electrical earthing system is presented. The idea behind this research is to furnish the general public particularly in Ghana to understand the effectiveness of using low resistive materials to provide low resistance values for their earthing frameworks to protect lives and guarantee hardware security. Right now, proficiency of materials accessible for free, to be specific, Palm Kernel Oil Cake (PKOC) and Tyre ash, as conductive inlay material for decreasing earth terminal resistance was assessed. Earth mat 20-cm length and 10cm breath were covered with each refilling material with their exhibition contrasted with reference to the earth mat additionally covered at a similar location with raw sand, specifically, sandy gravel at a specific area in Ghana. The outcomes show that tyre ash gives a steady earth resistance in both dry and wet climate conditions and improves it significantly as compared to PKOC. The main purpose of evaluating these two local materials as a backfilling agent is to reduce the earth resistivity which in this study was achieved successfully after 3 months of monitoring.
