Abstract The Gas Insulated Metal Enclosed Switchgear and Controlgear (GIS) is widely used in the power system, in the equipment installation and operation process, should be used in DC Voltage-Drop method of main circuit resistance measurement, to check the circuit-breaker, disconnecting-switch, the conductor connections. The as far as possible piecewise measuring circuit resistances of GIS, and how to carry out the long shaft line GIS circuit resistances test, put forward using the same interval other bus as a method of measuring circuit, ensure the test results under the premise of accurate and convenient on-site implementation, the same type of GIS in the circuit resistances test has a strong reference value.
