For the damped-oscillating waves, margins of the front time T1 and the time to half the peak T2 are 10 per cent whilst any value after the polarity reversal has to be less than 20 per cent of the peak value. Authors have tried to construct impulse current calibrator for reference measuring system, which would generate a waveform having the time parameters quite close to ideals.
After numerous simulations in selecting values for circuit composing components, authors came to an impression that a damped-oscillating current generator whose output waveform has parameter values close to standard. In the paper, authors' "impression" is theoretically proved and mathematically possible margins are to be presented in detail. Published in: International Power Engineering Conference. Article :.

Preview Abstract IEC applies to dielectric tests with alternating voltage; dielectric tests with direct voltage; dielectric tests with impulse voltage and dielectric tests with combinations of the above. This document is applicable to tests on equipment having its highest voltage for equipment Um above 1 kV. The third edition cancels and replaces the second edition, published in , and constitutes a technical revision.
