摘要
介绍了4PT接线方式二次接线改进后产生的现象,结合某站10kV PT二次回路实际录波图形,分析了电压畸变的原因、大小和相位关系,强调了消除这一影响的注意事项。
The phenomena of 4PT connection methods after the secondary connection improvoment is introduced.The reasons,size and phase relation of voltage conditions are analyzed based on practical waveform figures of 10kV PT secondary loop in substion.The relative items to solve effect are presented.
