This paper describes IMPREAL 2.0, a system developed in LabVIEW which automates the acquisition of voltage impulse waveforms from digital oscilloscopes and implements the mathematical procedures described in the new standards IEC 60060/2010. The system controls Tektronix oscilloscopes and is able to automatically calculate the time and amplitude parameters of lightning impulses, switching impulses,...
The International Electrotechnical Commission (IEC) issued in 2010 a revision of the family of standards IEC 60060, describing, among other requirements, how to calculate the various amplitude and time parameters used to evaluate high voltage impulse waveforms. However, the standards are not clear in some aspects, especially when describing tail chopped lightning impulses. This paper aims at describe...
