Atmospheric overvoltage statistics for studies of the coordination of substation insulation
Abstract
Stress induced by lightning on electric power installations is described. Rules for the variation of the physical parameters of these effects are given. Calculation of overvoltage in a substation and determination of the maximum allowable stress are covered. A calculation method for evaluating the statistical risk of these values being exceeded is presented. Lightning strikes close to the substation (up to 1500 m) and far from it are represented.
