The function of a Earthing system is to ensure that all electric equipment are connected to the ground potential. Hence, a well-maintained Earthing system ensures the proper functioning of protection systems and provided safety to operating personnel. The effectiveness of Earthing and lightning protection system may be reduced over a period of time due to physical damage, corrosion, adverse weather conditions or as result of addition or alterations to the building under protection. As such it is industry recommendation that a test and inspection is carried out yearly in order to cover all season over a period of time.
