Simulation and Impulse Testing Of Power Transformers at Different Values of Inductive Load by Using Spice Software

Abstract

Impulse generator is an indispensible high voltage set. It simulates the voltage due to lightning and switching surges and used for testing of insulation of various electrical equipments like transformer, insulators etc.The standard impulse waveform could be used to test the strength of electrical equipments against the lightning.Lightning characteristics and standard impulse wave form are related to each other.But the lack of relization about relation between them would make the solution to produce better protection against lightning surge becomes harder. The main object of this paper is to simulate the standard impulse waveform of the impulse voltage generator circuit at different values of inductive load and obtained results are showing graphically. The whole systems are studied in the PSpice software. The simulation circuit can be used to find out the desired front time, tail time, and peak voltage for different inductive loads.
