Your Single Source for Transformers

If you have an existing transformer and need repair, assistance, or a preventative maintenance program, contact us for assistance. For existing transformers, we offer field service including regular oil analysis and oil processing, if needed. However, TAW can provide much more. We offer turn-key project management, allowing you to maintain a single contractor for every phase of your electrical engineering project, from transformer design to build to install to inspection and to service. TAW supplies new and used replacement transformers.

Once your equipment is in place, as your full-service transformer partner, we are available to inspect and maintain your equipment throughout the life of your transformer. You can rest assured that we will take the time to identify problems at their root cause and then develop a custom solution to fix the problem completely. If your transformer is properly sealed and maintained you shouldn’t have to process the oil every few years, and it should run well with little intervention. The key, however, is preventive maintenance. It’s essential to conduct regular visual inspections and oil analysis to ensure there are no issues impacting performance.
