YS Engineering Solution offers comprehensive Transformer Overhauling services designed to fully restore the internal and external condition of power and Distribution Transformers, typically as part of scheduled major maintenance or after a fault. The overhauling process involves a thorough de-tanking (opening the transformer) to inspect the core and windings for any signs of damage, insulation deterioration, or loose connections. Essential internal work includes tightening the core bolts and winding leads, replacing worn-out gaskets and seals to prevent oil leakage, and installing new bushings or tap changers as needed. Following reassembly, the oil is processed through filtration, dehydration, and degasification, and the unit undergoes rigorous Transformer Turns Ratio (TTR) and Insulation Resistance (IR) testing to guarantee the complete restoration of its functional life and operational efficiency.
