Wayne 345-kV Ring Bus

Burns & McDonnell performed engineering design, procurement, construction, and construction management for a 345-kV ring bus project in Pennsylvania.

This substation contained a single 345-kV breaker and a 345/115-kV transformer. The project involved adding two new 345-kV breakers and creating a three-position ring bus arrangement. There was also a separate project to replace the existing transformer. The existing 345-kV line that passed through the station was a major link in the transmission system so all of the new work had to be completed with minimal outages on the 345-kV system.

Burns & McDonnell was responsible for all phases of design including foundations, oil containment, raceway, grounding, one-lines, schematics and wiring diagrams. The project involved the complete design, procurement and construction of the substation. Burns & McDonnell worked closely with First Energy to coordinate construction and outage sequences. Testing and commissioning functions were performed in conjunction with First Energy crews.
