| Abstract: | This paper details the maloperation process of WMZ-41 computer-based bus differential protection in a power accident.It analyzes the course of the accident and distinguishes different performances when bus connects branch CT.It indicates that bus differential protection would produce differential current after external failure is cut off.To pursue further perfect device function and more reliable device operation,this paper would supply some reference value. |

| Keywords: | computer-based bus differential motion maloperation differential current current mutual inductor |
