AMPED I provided the protection and control design for a new 345kv substation buses constructed next to an existing 138kv substation. The 138kv substation also needed to be upgraded in order to meet client’s requirement. The upgrade at existing 138kv substation included splitting the existing 2 x 138kv buses into a 3 x 138kv buses that required one additional 138kv bus tiebreaker to be added. The 138kv primary breaker as well as the addition of 6 x 138kv single bus-POT’s was also part of the new design upgrade.

• 1 x 345kv MOD control

• 1 x 345/138kv transformer protective and monitoring relaying

• 1 x 345kv line package relaying

• 3 x 345kV line potential transformers (POT’s) connection to relays

• 3 x 345kv single pole breakers control and relaying
