| Abstract: | LCD - 4 Relay is a differential relay of transformer. The false action of the differential protection not only can bring the unnecessary economy loss for users. but also influence safe operation of the whole electric power system. So analysing the cause of misoperating of the model LCD - 4 Relay has a significant meaning for the safety of production. |
