Service on Transformers (Repairs, Rewinds, Retrofit and Remanufacturing)  banner

Transformer Repair, Transformer Rewining, Retrofits and Remanufacturing

We are one of the few transformer repair companies in the world that designs and manufactures its own large scale rectifier-transformers and rectifiers in the same facility under one management team. This ability allows us to understand harmonics and losses very well.

Neeltran Inc. is completely equipped to handle all emergency and non-emergency repairs of transformers and power supplies. We repair ALL competitors units as well.  For retro-fit/replacement units, we can visit your site to ensure exact measurements and fit.

First, Neeltran Inc. will evaluate your unit. Then our engineers will electrically and mechanically enhance it before beginning the repair. This engineering review will help give the repaired unit a longer life.

Neeltran transformers repair should be serviceable for another 20 - 25 years. This is because an Engineered Repair involves a total redesign that seeks to eliminate original design weaknesses that caused the transformer to fail.

Neeltran will do more than simply copy the original design. Transformer rewinding and repair work requires design engineers with a high level of experience. We have a full-time engineering staff that specializes in transformer and rectifier design. Our engineers consider and evaluate: winding design, mechanical clamping, insulation systems, harmonics, core-steel and environment.  Our retrofit units will be designed to out-perform your original units.

Product Range for transformer repairs: Up to 60 mVA, Primary voltages up to 69 kV Oil Cooled.

34 kV and 15 mVA dry and water cooled. We service all types of equipment from OEM’s, Phase shifting, Rectifier, Regulating, Furnace Transformers and Reactors.
