摘要
阐述了自耦变压器操作波试验时 ,应根据变压器接线组别、变比、电压等级、中性点和绕组的绝缘水平、自耦变压器的特点等来选择试验接线 ,并讨论了加压和接地端、试验电压值在变压器操作波试验中的影响 。
Prior to switching impulse test being carried out, the test connection should be carefully chosen according to winding connection mode, ratio of transformer and its voltage class, insulation levels of winding and neutral point. A reasonable connection for switching impulse test is proposed on power auto transformer.
