| Abstract: | As to on-site fault line selection of power system with indirectly grounded neutral, its accuracy and application results are not satisfactory. Aiming at that problem and based on the characteristics of the system, the paper analyses the problems from the perspective of engineering application, and puts forward measures with which the errors can be reduced, and correctness and reliability of fault line selection can be improved. |

| Keywords: | power system with indirectly grounded neutral fault line selection zero-sequence current transformer error |
