Sažetak
The aim of the proposed paper is to present an effective numerical algorithm for the computation of Heidler function parameters. The basic six channel-base current quantities can be prescribed: current peak value, front duration, time to half value, current steepness factor, charge transfer at the striking point and specific energy. The approximation of the unknown three lightning current parameters for Heidler function is achieved using the least squares method. For the purpose of better convergence, the Marquardt least squares method has been applied. The proposed algorithm can be successfully applied for lightning current modelling in power engineering as well as in research on electromagnetic compatibility.
