Location : Barrie, ON

Year : 2012

Client : Black &McDonald

Project type : Double H 44kV / 13.8kV utility substation consisting of dual 30 MVA transformers. Engineers on record. Complete substation electrical engineering, construction package, COVER.

Scope : 

The Data Centre 44kV / 13.8kV utility Substation consisting of dual 29.4 MVA transformers; configuration with Main-Tie-Main transfer operation mode and two (2) lineups of 3 breaker Switchgears. This mission-critical utility Substation requires to supply the entire building load with abilities to transfer to and from two (2) utility source to achieve full redundancy.
As a mission-critical facility Substation, each transformer protection, secondary main and Switchgear have been located in separate buildings. An automated transfer schema allowed seamless transition between the separate incoming lines, transformers, Switchgear, and parallel operation. Transferred TRIP implemented with Local Utility.
