| Abstract: | T connected lines in the 110kV voltage are applied more widely.T connected lines face to the special problems of the current outflow of internal fault,easy TA saturation of outside fault,three-terminal operation and two-terminal operating mode switch,and so on.Combining the WXH-813A/T developed by XJ,this paper introduces the device applied to T-connected three-side with line differential protection principle and configuration,and then proposes the solutions of the T-connected line related to the special pr... |
