| Abstract: | A new method for the selective leakage protection system of high-voltage distribution network for mine using isolated neutral-point to ground — zero sequence current compensation method is presented in this paper. The theoretical analysis and experiments show that the method is easily implemented in the protection of a microprocessor based on simple, reliable operation and high sensitivity. |
