Generation Oscillating Switching Impulse Using Power Transformer

Abstract:

According to IEC60060-1, IEC60060-2 requirements, on-site tests for the high voltage apparatus can not be achieved due to many external factors such as the huge impulse voltage source and external electrical and magnetic fields, weather condition, etc. Therefore, IEC60060-3 points out the impulse waveforms for the high voltage apparatus during on-site tests, one of the impulse waveforms is the oscillating switching impulse, but the oscillating switching impulse source with high amplitude is a bulky test equipment which is not suitable for the on-site test, consequently the demands for portable oscillating switching impulse source is urgent. This paper presents that the high oscillating switching impulse voltage can be generated by a low oscillating switching impulse voltage with the power transformer which is the test object, the simulation and experiment results show this method can be used for the power transformer during oscillating switching impulse on-site test.
