| Abstract: | With the national economy rapidly developing, load is continuously increasing on electric power lines and the zero sequence current is greatly increased on power line operating with phase failure.The paper calculates and analyzes the zero sequence current in power line during phase failure,meanwhile,it presents the problem to notice and the way to solve it when protection is set and operated under such cases. |

| Keywords: | phase failure protection zero sequence current |
