Performance Evaluation and Consideration of the UHV IVG

UHV IVG의 성능평가 및 고찰

This paper, as a preliminary study, presents the important consideration in laboratory planning and designing 4.2MV impulse voltage generator(IVG), which enable to test and evaluate the UHV dielectric performance of power electric apparatus up to 765kV-class. To fix and confirm the kinds of loads and their capacities to be tested by KERI hereafter, wide investigation and an analysis of test objects, especially heavy electric apparatus of Korea, according to their ratings and test voltages have been conducted. With the special consideration concerning other matters in designing of 4.2MV IVG have been described with the practical examples and references.
