High resolution impulse analysing system

Abstract

An impulse is an intentionally applied aperiodic transient voltage or current which usually rises rapidly to a peak value and then falls more slowly to zero. The aim of this project is to analysis of the lightning impulses according to IEC 60060-1: 2010. The main purpose of developing the system is so that it is comparable to Haefely High Impulse Analysing System 743 (HIAS 743). LabVIEW program has been developed to analyse key parameters normally front time, time to half, peak value, of full and chopped lightning impulses. The program has a procedure for obtaining the parameters of the impulse waveform. The system has been tested with impulse voltages up to 500V. This system also accommodate the use of attenuators Attenuator Type 9410-1. Contribution from this project is that, it is a cost saving project, where to develop this system equipment that is need is a laptop to read the impulse waveform. Besides that, portability is one of the main issues, by developing this system, the high voltage equipment can be tested at the field with no hassle.
