In the proposed measurement

a second-order non-oscillating circuit composed of a super capacitor

a standard resistance and tested components discharges kA-level impulse current. The peak current and the corresponding voltage drop of the GIS conductor pole are used to get the loop resistance in order to eliminate the impact of the inductance on the measurement result. Simulation

laboratory test and field test verify the feasibility and accuracy of the proposed method for measuring the loop resistance of GIS conductor pole via impulse current. In the field test

the proposed method gives more accurate loop resistance

compared to the DC voltage drop method.
