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, like a blood test or a scanner examination of the human body can provide warning of impending problems, giving an early diagnosis and increasing the chances of finding the appropriate cure. Gas analysis is a complete gas chromatograph rather than a “go-no-go” test, hence a true indication of the internal condition is possible.
The yearly monitoring of transformer oil will provide an indication of the rate of gas generation within the transformer and can be a useful tool in determining the on-going health of an operating transformer.
The following nine key gases are analyzed to detect sign of corona discharge, overheating, insulation failure, arching etc.
• Hydrogen
• Oxygen
• Nitrogen
• Carbon Monoxide
• Methane
• Ethylene
• Ethane
• Acetylene
• Carbon Dioxide
