Transformer Overhauling services by YS Engineering Solution represent a comprehensive, major maintenance procedure aimed at fully restoring a Transformer to its near-original operating condition. This process is far more intensive than routine repair, typically involving the complete untanking and dismantling of the core and coil assembly. The overhauling includes meticulous cleaning to remove sludge, hot oil washing, detailed internal inspection of windings and core integrity, and necessary repairs like tightening or re-insulating components. Critical activities also encompass replacing all oil sealing gaskets, conducting full oil processing (filtration and degasification), and replacing worn-out accessories. The process culminates with thorough pre-commissioning electrical testing to ensure peak performance and significantly extend the transformer's service life, often by years.
