Validation of a System for Evaluation of High-Voltage Impulses According to IEC 60060:2010

摘要

This paper describes IMPREAL 2.0, a system developed in LabVIEW that automates the acquisition of voltage impulse waveforms from digital oscilloscopes and implements the mathematical procedures described in the new standards from the International Electrotechnical Commission IEC 60060:2010. The system controls commercial digital oscilloscopes and is able to automatically calculate the time and amplitude parameters of lightning impulses (LI), switching impulses, chopped LI, and oscillating impulses (lightning and switching) waveforms, generating test reports tailored for the needs of the calibration and tests labs. The estimated uncertainty due to the software processing is also presented here, following the guidelines defined by standard IEC 61083-2:2013.
