| Abstract: | The relay protection solutions of cross line fault over double-circuit lines on the same tower are discussed, the protection signal transmission modes and technique characteristics of longitudinal differential protection are introduced.For a practical project, ideas of scheming the relay protection for double-circuit lines on the same tower and choosing the telecommunication channel are analysed. An interface circuit between power line carrier and relay protection device is presented to implement 3+1 command mode. |

| Keywords: | double-circuit lines on the same tower longitudinal differential protection optical fiber |
