Y S Engineering Solution specializes in Transformer Overhauling, a comprehensive maintenance procedure essential for restoring a transformer to its optimal operating condition and significantly extending its operational life, often recommended after a decade of service or following an internal fault. Their meticulous process involves a complete shutdown and draining of the oil, followed by dismantling the unit for a thorough inspection and cleaning of all internal components, including the core, windings, and bushings. Technicians perform necessary repairs such as winding rewinding, replacement of critical wear parts like gaskets and bushings, and the servicing of tap changers. A vital step is the Transformer Oil Filtration and Testing to remove moisture and contaminants, after which the unit is refilled with new oil and subjected to final re-commissioning tests, such as insulation resistance tests, to ensure the revitalized transformer operates efficiently and safely.
