In high voltage measurement digital measuring system is widely used for its attractive features, for example automatic data acquisition. However, the accuracy in the measurement of both the amplitude and time parameters by digital measuring system is not known in detail, especially in the measurement of single-shot waveforms.
In this paper, the accuracy of the peak value and the virtual front time of the standard lightning impulse without any signal processing of raw data is shown. From these results, the required characteristics for digital measuring system to satisfy the IEC Draft on digital recorders for measurement in high voltage impulse test techniques are shown. In addition, the accuracy of the peak voltage and the rise time of the Gaussian pulse is shown.
