Jubail -2 Sub-3 Energization

This station successfully energization without any small problem 25 & 26 on June 2012.
Really i got good confident on the work and well experience.
We got good team during commissioning and its lead us to success.
Note:-
The total bay portion of Line and transformer feeders are protected by there own relays
The spare feeders are protected by only busbar protection and it will cover up to CB line side CT.
During first time charging we need to protect the spare feeders up to Air bushing.
Generally two methods are following to protect the spare feeders.
1. If short the CB line side Busbar CT then busbar protection will cover upto Air bushing.
2. Change the other end (Existing end ) protection relay Zone 2,3 time settings to zero and it will cover upto New station spare feeder air bushing.
