Waukesha® Service can deliver the peace of mind you need! Waiting for a service outage to occur in order to assess your power equipment is NOT an option. Your customers need reliable electric power and your substation transformers and equipment must be in top condition to deliver. Take the time now for a comprehensive power equipment check-up by contacting your SPX Transformer Solutions representative.

Our condition assessments can help identify the present condition of your transformers and their components, estimate remaining life, make life extension suggestions and help with economic decisions for future repair or replacement actions to improve the performance reliability and extend the life of your assets.

Operational History

  • Maintenance records
  • Loading history and overloads
  • Short circuit history

These analyses will be made using the latest state-of-the-art design programs, including Finite Element Analysis (FEA) and thermal design programs. Also, any upgrades that can be made will be suggested to allow you to bring your Waukesha® or other brand power transformer up to current design standards.
