Prediction of transient electromagnetic environment in power networks

Abstract

In this paper the authors suggest exact analytic formulations which allow numerical characterization of the transient electromagnetic environment, during operation of circuit breakers or disconnecters, of an electric power transmission network. In this work, an exact method for calculating the transient field radiated by an air insulation substation (AIS) together with the strictest formalism which enables the same calculation to be made for a power transmission line are paid particular attention. Results of simulations for different examples together with results of measurements complete the study.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
