Protection against lightning surges of electrical and industrial installations

S. Trabulus YTU , Erdin Gökalp YTU

Abstract

Lightning strokes generate high interference voltages in industrial installations and high-voltage substations. The characteristics of the transients, the amplitudes of the voltages and their number vary considerably from one network to another. A sound understanding of the phenomena involved and of the implications of certain industry practices are necessary to ensure the safe and reliable operation of the installed electrotechnical equipment. In this paper a look is taken especially at effects of lightning strokes on power distribution system, design of distribution class surge arresters for lightning protection and main design criteria for insulation coordination from the viewpoint of lightning protection.
