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.
