Abstract

Rwanda has experienced many damages for many years, including life losses, severe and minor injuries of humans, animals and infrastructure due to lightning strikes. According to the Rwanda Ministry of Disaster Management and Refugee Affairs (MIDIMAR) statistical records from 2011 to 2015 and NASA satellites records, have classified Rwanda among the top high risk regions affected by lightning strikes, hence there is a need to mitigate the effects of lightning strikes. One of the best ways to protect lightening strikes is to have high quality grounding. The soil resistivity is one of the key factors that influence the performance of a grounding electrical installation. In this work, we used Four-point measurement method to measure the soil resistivity. Using this method, ground resistance measurements in four provinces out of five of Rwanda were measured and data recorded where their corresponding soil resistivity values were calculated. The measured, calculated and recorded data may be used by different institutions in the design and implementation of their lightning protection systems in the country.
