| Abstract: |
| The erection modes of power transmission lines partially on same tower are briefly introduced and the fault characteristics are compared among power transmission lines totally，partially and none on same tower，based on which，the influences of fault location and erection parameters on the zero-sequence current protection for the power transmission lines partially on same tower are researched and the improving measures are proposed. The simulative results show the correctness and effectiveness of theoretical analysis and the proposed countermeasures. |
| Key words: AC power transmission power transmission lines partially on same tower zero-sequence current protection relay protection |
