The application of series resonance system in cable voltage test
He Bo · Electric Wire & Cable · 2002
The common commerical frequency voltage test apparatus are divided into two categories, namely the traditional step up transformer system and series resonance system. This peper presents the features of the two kinds of test apparatus, focusing on the work principle, construction and characteristics of the series resonance system. It indicates that compared to the traditional step up transformer system, the series resonance system has a lot of advantages for the commercial frequency voltage test of high voltage, large size and large length power cables.
