Over time electrical systems can become outdated and, in some instances, even pose a safety risk due to aging or inadequately rated equipment. This was the situation at a major lumber processing mill located in Oregon. As the processing mill grew, their existing outdoor substation could no longer handle the current and projected loads. The key issue, however, was how to go about updating this equipment without significant downtime to the facility. We started with conceptual planning documents to identify the sequence of the projects and associated budgets. Once the client had all options, we then followed through with multiple design projects including major upgrades to the entire medium and low voltage electrical systems.
Some of the various design components for the new main substation consisted included:
- New 12.47kV Circuit Breakers
- 21kV/12.47kV Padmount Transformers
- 12.47kV Cable Distribution to Plant Power Centers
- Telemetering for overall Energy Monitoring
- 21kV and 12.47kV Line Termination Equipment
- Grounding System
- Oil Retention Pads, Fencing & other Related Items
