One Transmission Line Tripped
When one transmission line to PEA/EGAT substation is faulted and tripped, Power plant will be operating in island mode, if the bus tie CB BYB-01/7002 is not in closed position, to supply power to plant auxiliaries and all IU customers.
When the fault in troubled line has been cleared and line is ready for service, PEA/EGAT will charge
line from PEA/EGAT substation. The re-synchronization will be done at Terminal
Substation, 1YB/7012 or 2YB/7022 depending on which line is to be synchronized.

be referred to section 4.3.1.1.
