9.2.1 NORTH BUS ZONE
With reference to the following diagram, the North bus differential zone is bounded by the following CTs: CT-1, CT-2 (if S-1
closed), CT-3 (if S-3 closed), CT-4 (if S-5 closed), CT-5 and CT-8. The North bus protection should operate the following
breakers: B-1, B-2 (if S-1 closed), B-3 (if S-3 closed), B-4 (if S-5 closed), B-5 and B-7.

9.2.2 SOUTH BUS ZONE
The South bus differential zone is bounded by the following CTs: CT-2 (if S-2 closed), CT-3 (if S-4 closed), CT-4 (if S-6
closed), CT-6 and CT-7. The South bus protection should operate the following breakers: B-2 (if S-2 closed), B-3 (if S-4
closed), B-4 (if S-6 closed), B-6 and B-7.
