Abstract :
The lightning impulse voltage calibrators, developed at National Measurement Laboratory (NML) and MIKES-HUT, and a recently developed commercial digitizer were compared. With this three-way comparison, not only the accuracies of the devices were compared, but also the linearity of measurement of both peak voltage and time parameters was investigated. The results demonstrated that the linearity of the calibrators is superior to that of the digitizer.
