Total maintenance solutions for transformers and critical infrastructure

IPS is a total maintenance solution provider for large industrial power consumers who own transformers. We have the engineering and resources to improve system uptime and reliability with both new and legacy assets.

Our transformer specialists repair, refurbish, and rewind all OEM transformers:

  • Power & Auxiliary
  • Mobile
  • Arc furnace
  • Voltage regulating
  • Rectifier
  • Dry type (recondition & refurbish only)

In-shop repair handles transformer service and repair on transformers up to 60 MVA auto/230 kV class. In the field, we service and repair generator step-up transformers rated up to 345 kV and exceeding 1,000 MVA.

IPS engineers and technicians develop plans for outages and availability of service. They can help manage regulatory compliance and project costs, and work with your maintenance and reliability engineers to implement system upgrades.

To discuss your operations’ transformer performance requirements, talk to your local IPS representative or contact us.
