According to the transmission conventional ratio differential protection, complex ratio differential protection and fault component complex ratio differential protection that in common use on the protection of Transmission line,ATP-EMTP method of simulation software simulation is used. The criterion of transition resistance ability of the conclusion of the combination of these three criteria by high resistance fault test is concluded ,in order to solve the reliability and sensitivity of the differential protection.
