YS Engineering Solution offers a highly specialized Transformer Overhauling Service, which is a comprehensive restoration process designed to bring aging or faulty transformers back to their peak operational efficiency. Serving the industrial and commercial sectors of Gurugram and Delhi-NCR, their overhauling procedure goes far beyond routine maintenance. It involves a systematic disassembly of the unit, followed by the untanking of the core and windings for a deep internal inspection. This allows their engineers to identify hidden issues such as axial shrinkage of windings, sludge accumulation at the bottom of the tank, or degradation of the core-bolt insulation.The overhauling scope at YS Engineering Solution includes the meticulous cleaning of the core-coil assembly using hot oil jets, followed by vacuum drying or impedance heating to eliminate deep-seated moisture from the insulation. Key components such as gaskets, bushings, and breather systems are typically replaced with genuine spares to ensure a leak-proof and airtight seal. The process concludes with high-vacuum oil filtration to restore the oil's dielectric strength, followed by a rigorous battery of post-overhaul tests including Polarization Index (PI), Voltage Ratio, and Magnetic Balance tests. By adhering to strict IS 1866 and IS 2026 standards, YS Engineering Solution significantly improves the Insulation Resistance (IR) values of the asset, effectively extending its service life by years and preventing catastrophic facility-wide power failures.
