Overhauling
Why do transformers need Overhauling?
After a great period of operation, mechanisms start to wear down by nature. This common situation, however, can lead to a critical breakdown and result in a cost-demanding repair. Hence, being one step ahead and preventing the damage is key to lucrativeness. The objective of overhauling is to keep the system operative. Systematic and frequent checks can impede all kinds of severe damage. The overhauling process is requisite to strengthen the life of the Transformer.
We have all the required resources like state-of-the-art equipment and efficient manpower to cater to the Transformer Overhauling Service. We can devise interval-based maintenance which can substantially help in lowering catastrophic breakdown. This service can also be tailored as per the requirement of the patrons.

Transformers will give trouble-free service for a long time if attention is paid to the given factors.
A proper record of all the observations, repair, and maintenance operations will warn of any impending troubles.

The Entire Process
The entire process is commenced by dismantling the whole transformer and repairing its core elements if any damage is found. The method embodies basic inspection, following removal of the top cover, then core from the transformer, heating the core with oven or electric heaters for moisture removal, changing gaskets of a transformer, and eventually assembling the whole transformer back with utmost care. The processing time varies according to the size of the transformer. The overhauling procedure is carried out in the following stages.
- Inspection
At the outset, the transformer will be meticulously inspected. Our experienced crew conducts an inspection on the overhauled transformer under development conditions. The overall performance is observed while the transformer is in use. This approach allows one to encounter the major issues and perform the troubleshooting more fruitfully.
- Disassembly
Once the complete inspection is done, the parts of the transformer are carefully dismantled. Disassembly is paramount for the following steps of the overhauling process, i.e repair. Our skilled workers take the responsibility of putting the transformer down adeptly, demonstrating which parts need to repair or replace.
- Repair
Based on the issues found, the transformer is either repaired or certain damaged parts are replaced. This stage clearly shows how beneficial overhauling is as opposed to replacing the whole equipment at once. Replacement of parts might take longer than a simple repair, as the spare parts might need to be ordered from a manufacturer.
- Reassembly
After the proper replacement of spare parts, reassembly of the whole transformer is performed. Reassembly, being one of the most crucial stages for the operation of the pieces of equipment, it’s best handled by our specialists.
- Testing
The final step concludes the overhauling process. Without testing it is absolutely impossible to identify if the performed repair was effective. During testing the retrofit is either proclaimed successful or – less frequently – the process goes back to the starting point (inspection).
Our engineering crew inspects each and every part of the transformers after its complete dismantle and rectifies the defects found and bring it back to its original condition for an error-free, safe and streamlined operation.
