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 Prolec GE Waukesha 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.
