TRANSFORMER SERVICE

More than just servicing transformer, we make your transformer like new.

Nothing is impossible when it is known that SWTS, a former Westinghouse company, has been servicing power transformers for decades.
Repairing transformer requires expertise.

Proudly, we are into the fourth decade of providing on-site service with quick repair turnaround to eliminate the high logistical cost associated with working on Transformer.

On Site Services
Our on-site services comes with State-of-the-Art portable CLEAN-ROOM and equipment so that you can be assured of quality work. We provide total transformer service from an initial site inspection and information gathering to oil filtration, tap changer repair, bushing repair, coil repair and general overhaul, upgrading and rewinding.

Oil samples are drawn from the transformer and tested for di-electric strength, water, acidity and dissolved gas content. Gas analysis can provide warning of impending problems and increases the chance of finding the appropriate solution.
