North Appleton Substation 345kV Substation

Realtime provided testing and commissioning services to expand the North Appleton Substation and reconfigure the existing substation to an 8-position 345kV breaker-and-a-half bus arrangement, with provisions for expansion to 10 positions.

The existing (4) 345kV lines were reconnected to the new substation configuration. A new 345kV line connection was also installed. The equipment included with the existing 345kV ring-bus arrangement will be removed in conjunction with building the new 345kV breaker-and-a-half bus arrangement.
