Abstract:

The through-flow experiment in the simulated state of earth fault of various alloy materials were done, the variable parameters of resistivity were obtained. In the paper,the characteristics and its variational causes of alloy materials resistivity in the state of earth fault were analyzed. At the same time, the choice principle of resistance material, which can be used in Low resistance grounding resistor, is presented. The research results are useful for the design of Low resistance grounding resistor.
