| Abstract: | A new wiring mode of busbar differential protection , that is , single bus section with main wiring on bypass mode is proposed in this paper. It makes the bus protection functions be implemented easily, simplifies the switching operation of the bus differential protection as the operating mode changing, reduces the possibility of outage expansion by bus fault due to miss-operation, and improves the reliability and availability of the protection equipment. |
