Project : 100 MVA, 138 kV/34.5 kV Substation Expansion, Grandview Cogeneration

Transcanada Energy/Irving Oil — Saint John, New Brunswick

CHA Canada performed design modifications to the 138 kV Substation #3 to incorporate new interconnected star grounding transformers, including determination of transformer rating. The project modified the 34.5 kV and 138 kV protection and breaker closing circuits to incorporate the generator synchronization schemes and extended the 34.5 kV substation switchgear lineups to accept two 45 MW gas turbine generators.
