Assessing Partial Discharge on Composite Insulators Under Desert Pollution Conditions

Abstract

Transmission lines located in the Sinai desert are subjected to desert climate, one of whose features, especially in the spring, is sand storms. Line insulators are thus exposed to sand contamination, which may produce streamer discharges in the air surrounding insulator surface. Such discharges may lead to flashover. This paper examines the electric field… (More)
