RETROFILL

Transformer Retrofill

PSS retrofills power transformers with a variety of fluids based on the specific application and individual needs of the customer. We evaluate your oil for flash point, quality and other potential issues, and recommend various fluid options to correct any problems.

For small, mineral oil filled transformers it is often less costly to retrofill the oil rather than undergo a hot oil reclamation process. For larger substation transformers, replacing the mineral oil with a biodegradable fluid, such as Envirotemp FR-3™, saves money over building a firewall.

Replacing PCB-based fluids in existing transformers can help to improve the life and reliability of the transformer, reduce environmental hazards and increase fire safety.

Each project has unique factors that must be considered when developing an action plan. Weather, load, environment, location, and equipment design all must be taken into consideration. Our engineering staff has extensive experience and expertise in finding the right solution for all your retrofilling needs.

Retrofilling—or replacing PCB-based fluids in existing transformers—can help to improve the life and reliability of the transformer, reduce environmental hazards and increase fire safety.
