Abstract [en]

The Marquardt least-squares method is applied in this paper for estimation of the Pulse function’s non-linear para­meters in order to approximate measured lightning currents. Such procedure is generalized so it could be used for other pulse functions representing lightning current waveshapes. The obtai­ned results show that this method provides good results for the IEC 62305-1 standard lightning current waveshapes of the first and subsequent return stroke currents, and also for some measu­red fast- and slow-decaying current waveshapes.
