摘要
Abstract
Before No.3 main transformer of 500 kV Xiangshawan Substation put into operation, protection phasor test is carried out to measure the amplitude and phase angle with phase meter on the side of 500 kV and 220 kV. Compare with the previous calculated value, and combine with the sample and the uneven flow value of different prodection device to determine the correctness of the prodection ratio differential, side differential and busbar differential of No.3 main transformer.关键词
