IEC 60060-1 Requirements in Impulse Current Waveform Parameters

Shuji Sato
There are IEC 60060-1 requirements on three impulse current waveforms. 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, cannot be realised. In the paper, authors' "impression" is theoretically proved and mathematically possible margins for the parameters are to be presented in detail.
