Open full text 0 citations

Abstract

International Standard in high voltage measurement handled by IEC Pub. 60-3 (1976) has been pointed out that its requirement is not sufficient in the impulse voltage measurement accuracy, especially in front-chopped impulse.And its revisory work has been executed by IEC Technical Committee. Corresponding to this work, the unit step response of a resistive voltage divider is discussed by the comparison of the measurement with the calculation by EMTP, to establish the simulation procedure by EMTP, in this paper.Then, this EMTP simulation is utilized for the calculation of measured voltage in the virtual impulse voltage tests (full and front-chopped), and the measurement accuracy is discussed taking into account of various time parameters of measuring system, to help understanding of the revision.
