Gasket replacement in a transformer is a vital maintenance activity aimed at preventing oil leakage and moisture ingress. Gaskets are sealing components placed between flanges and covers in transformers, typically made of rubber or cork-based materials. Over time, these gaskets can deteriorate due to aging, heat, and oil exposure, leading to leaks or loss of insulation integrity. During replacement, the transformer is de-energized, oil is partially drained if necessary, and old gaskets are removed and replaced with new, compatible ones. Proper installation ensures a tight seal, maintaining internal pressure and oil quality. Timely gasket replacement enhances transformer reliability and longevity.
