| Abstract: |
| With the investigation and analysis of a fault, this paper explains the operation of optical fiber permissive relaying protection and the course of sending permissive signal. Especially, the operation logic whether or not to accord with design requirements.What the operators should do when the protective relay operates. |
| Key words: high-frequency protection permissive signal directional element |
