Abstract
In this paper, a new method for estimation of time parameters of standard and non-standard switching impulse voltages is presented. Method is based on estimation of time difference between true and virtual origin of the switching impulse waveform. An analytical expression was derived for calculation of time to peak, which is more accurate than the expression given in IEC 60060-1. The presented method was verified with mathematically generated double-exponential waveforms and waveforms given in IEC 61083-2 with time to peak values within the range 20-300 µs and time to half values within the range 1000-4000 µs. An experimental verification of the proposed method was successfully demonstrated by comparison with an approved impulse voltage measuring system.
