Curve Fitting for Lightning Impulse Tests According to Standard IEC 60060-1:2010 by Levenberg-Marquardt Algorithm

Abstract

The International Electro technical Commission (IEC) IEC 60060-1: 2010 describes the requirements and how to calculate impulse waveform parameters. This paper proposes a curve fitting methods for determining the lightning Impulse voltage waveform parameters according to Standard IEC 60060-1:2010. Curve fitting is important for waveform parameter evaluation in testing and research on high voltage engineering. This paper presents a method to estimate the waveform parameters according to the standard IEC 60060-1: 2010. Levenberg-Marquardt algorithm has been applied for this purposes. The standard lightning impulse waveform generated by the test data generator attached with IEC 61083-2. It found that the developed software can be used in the waveform parameter evaluation accurately.
