INTRODUCTION


The production of lightning arresters using locally available materials in Nigeria was carried out Usifo and Edeko (1998). They used a mixture of haematite and calcium carbonate to produce the arrester. Usifo (2001) conducted s further work on these materials which resulted in the present day Oriaghe (named after the inventor) lightning arresters which have the same characteristics as that of the silicon carbide based lightning arrester. It would be interesting to note that these lightning arresters were the spark gap types which have several fundamental limitations (Paul and Venugopalan, 1993). These limitations include the valve elements, the gaps, and the power followthrough current. It has nonlinearity coefficient in the range of 2 to 6 and negative temperature coefficient.
