Installation

No matter what electric transformer you’re using, from power to distribution transformers, proper operation is impossible without a correct installation. With the proper procedures and execution, our engineers will ensure your transformer is installed correctly. Our attention to detail sets every transformer on the right path to functioning as efficiently and safely as possible.

Site considerations, controlling the sound level and ensuring every connection is tightened are other aspects we’ll take care of during your initial electrical transformer installation. A final testing is an essential step of installment. Our engineers will ensure all connections are secure, and the correct ratio between low and high voltage windings is present.

Commissioning

Commissioning is another crucial point of a transformer’s life cycle. A rigorous testing process is conducted after the transformer is fully installed, to check if the transformer is performing exactly as it should. Our professional engineers and skilled workers will uncover any problems or faults that may have occured during installation.

Results from the commissioning are also essential for future use. They are used as a baseline result, and are critical components to help diagnose any problems that come up in the future.

Maintenance

We strongly recommend regular maintenance for your transformer. Regular preventive maintenance will let you stay one step ahead of any potential issues that could develop within your transformer. Typically, the insulation system is the first component of a transformer to be affected.

Organic products within a transformer degrade the fastest, and become less and less capable of handling the stress of their daily operations. Left unattended, these small issues could develop into major faults and cause a transformer to fail altogether. Paper insulation degrades quickly, and rewinding might be needed to restore it to its best.

Our expert engineers will conduct thorough checks to uncover any potential or present faults within your transformer. Annual maintenance services will address any potential issues and remedy them with preventive actions, guided by our engineers’ wealth of expertise and experience.

Revitalising mineral oil can be done with oil reclamation. This results in the organic materials performing closer to what they did when they were new.

Repair

If your electrical transformer has failed or is displaying noticeable faults, our professional and expert engineers will conduct several test to decide if overhauling your transformer if necessary. When overhauling, rewinding a transformer with new paper insulation lets it perform as optimally as possible.
