The Voltage and Time Parameter Measurement Uncertainties of a Large Damped Capacitor Divider due to its Non-ideal Step Response
نویسنده
چکیده
Limited frequency response of impulse voltage dividers contributes to the measurement errors of the peak voltage and time parameters. This paper investigates the convolution method for the determination of the errors of lightning impulse parameters due to non-ideal step responses. The step response of a damped capacitor divider with a voltage rating of 2.2 MV was measured and analytical lightning impulse waveforms were used in the analysis. The paper concludes that the errors calculated with the convolution method can either be used for correcting the measured impulse parameters or as uncertainty components for estimating the measurement uncertainties of the impulse parameters.

Using Deconvolution for Correction of Non-ideal Step Response of Lightning Impulse Digitizers and Measurement Systems
Lightning impulse measurements can be highly influenced by measurement arrangement, characteristics of high voltage divider, digitizer (transient recorder) performance, and algorithms used for parameter evaluation. The main sources of measurement errors are the non-ideal step responses of digitizer and voltage divider. This paper discusses the use of deconvolution to correct for the non-ideal s...
