Abstract: This paper introduces a traceable impulse voltage generator which can generate standard lighting impulse and switch impulse waveforms according to IEC 60060——1∶2010. It is used to calibrate the time parameters and peak value for digital recorder and digital peak value voltmeter. The estimated uncertainty for the impulse peak value is less than 0.1% and for time parameters， lass than 0.5%. It can be traced to national compnent standard by theoretical analysis. It can satisfy the parameters calibration requirements of digital voltmeter and digital recorder used for measuring lighting waveform. It is of great practical use and can be used widely in impulse measurement calibration.
