Transformer Overhauling is a comprehensive maintenance procedure to restore a transformer's original performance and extend its lifespan. It involves a detailed process of dismantling the transformer, inspecting and cleaning internal components like the core and windings, and performing necessary repairs or replacements. Key tasks include oil filtration, replacement of worn-out gaskets, and functional checks of all protective devices. Overhauling is typically done on a scheduled basis or in response to a major internal fault to prevent a complete breakdown.
