Review of Lightning Impacts on Power Supply of Productive and Extractive Industry in South Africa and Such Ways of Production Loss Mitigation as Installation of Line Lightning Protection Devices

Abstract

This paper focuses on a review of lightning resulted issues in electric power supply of productive and extractive industry in South Africa. The article presents the interview result among representatives from companies in the industry above. Analysis of interviews showed that it is essential to prevent any interruptions of technological processes. Possible ways of lightning consequences mitigation are presented. Line lightning performance before and after installation of lightning protection means is being evaluated. Also the paper presents an economic analysis of such protection benefits based on mitigation of production losses by reduction of lightning outages quantity and their cumulative duration.
