Protection of gas insulated substations against lightning overvoltages
Abstract
Selection of protection devices (air gaps, open arresters, encapsulated arresters) and their locations so as to bring lightning overvoltages below tolerances for electricity substations is discussed. A calculation method for evaluating the statistical risk of these tolerances being exceeded is presented. Methods for representing substation system elements in computerized simulation models are outlined.
