Olsson Industrial Electric, OS Engineering and Olsson Controls together expanded and upgraded Seneca Sawmill’s power distribution system (designed and built by Olsson) in Eugene, OR. This $3M expansion project consisted of relocating and installing 12.47kV overhead to cable risers; installing new medium voltage circuits in vacuum fault interrupter duct banks; installing new 15kV, six-way pad-mounted switch and switchgear; installing seven 1000kVA to 2000kVA–rated substation transformers and installing a range of 480V switchgear and switchboard components.
This project also included the installation of a 2000/2300 kVA, Class I, 3-Phase, oil-immersed transformer. The transformer was tied into the existing system with the primary connected to 15kV switchgear and the 480V secondary feeding a new compressor/sorter/stacker line via switchgear. The transformer was installed in an active sawmill without any safety incidents or unintentional process interruptions.
