Hundred percent reliability is the utmost desire of every electricity operator, therefore a good designer will always aim at giving the optimum reliable conditions. This requires choosing the best and suitable materials according to the required regulations. The Niger Delta environment, due to its peculiar terrain and harsh climatic conditions requires special attention in terms of choosing the materials in construction. Therefore, a good protective device is necessary not only for equipment but also for personnel. The climate of Niger Delta is known to have heavy rainfall, high humidity and high Isokeraunic level, therefore proper selection of Surge Absorber (diverter) is necessary for a reliable protection from travelling waves and switching surges in lines and substations. The aim of the paper is to study the performance of surge diverters and identify the diverter that is best suited for both performance and construction in this harsh environment. From the records ZnO (linear) arrester has better performance but the type and place of usage determines the reliability (life span) of the diverter. Due to dust and rainfall, the external material is also a major factor in determining erosion of material and watt losses. It is therefore necessary to suggest some maintenance procedure that may help extend the life span of the diverter.

Author Keywords: Protective Ratio, Gapless metal Oxide, Surge diverter, Basic Impulse level, Hydrophobicity, Polymer housing.
