| Abstract: | The maloperation of pilot protection caused by zero-sequence mutual inductance when earth fault occurring in parallel lines is analyzed. Through the accident, the paper presents that zero-sequence mutual inductance will influence directional components. And the relevant countermeasures are put forward to enhance the fault diagnosing ability of relay protection engineers. |

| Keywords: | parallel lines zero-sequence mutual inductance pilot protection |
