摘要
介绍了PT断线的几种情况 ,分析PT断线的判据 ,提出二次回路防止失压误动的措施 。
The paper presents several events of PT broken line and analyses the criterion of them.It offers steps of the secondary circuit to avoid miss operation when the alternating voltage losing, especially a measure to improve the double busbar voltage switch circuit with two position relay.
