Novel Application of LabVIEW in High Voltage Engineering

Abstract

High voltage equipments are often placed in open air and they are often exposed to lightning strike as well as surge voltage. Most of such high voltage power equipments are placed in the power transmission line. They are sustaining high surge voltage during the lightning phenomena. To protect all such power equipments and quality power supply
the study of lightning characteristics is most important for every power engineers.
Lightning impulse voltage and standard impulse voltage (1.2/50 μs) are similar to each other. So, to achieving better protection of high voltage equipment, study of impulse voltage waveform is very important. A comparison has been made between standard impulse waveform obtained by simulating Marx impulse generation circuit in LabVIEW
Multisim and practical Marx circuit. This impulse waveform can be used to test the capacity of electrical equipment against the lightning and switching surge voltage.
So, generation and simulation of an impulse wave has been carried out by the help of LabVIEW Multisim Software Package. A practical Marx circuit has been made and its
comparison has been drawn with standard impulse voltage. Data acquisition of the practical impulse voltage generation circuit has been performed.
