Abstract: The power associated with Lightning are enormous and unpredictable, controlling and directing the Lightning energy to protect humans, buildings and equipment is a thing of concern to Electrical Engineers. Earthing and Lightning protection system is a life wire of any Electrical safety.There is no convincing evidence that lightning can be prevented, so, one must design a facility byresponding appropriately to make lightning strikes harmless.Lightning protection system is a system put in a place for protection against overvoltage.In this study, diverse factors that affect earth electrode resistance for effective performance was investigated. Based on the investigation, different methods of earth electrode resistance reduction were compared. In comparison, factors that differentiate various methods was ascertained, and some of the methods were found to have common factors that canreduce resistance when applied while others have different resistance reduction factors all together.Merits and demerits of the different methods were identified, and the identification of those merits and demerits suggest the method that is ideal in an environment for effective performance as conclusion.The study concluded that no method overshadows another method as different methods suits different environment where it is most preferred and effective.
Keywords: Comparison, Similarities, Differences, Merits, Demerits, Methods.
