Transformer Oil Filtration

 Transformer oil filtration is a critical maintenance process that removes moisture, dissolved gases, sludge, and solid contaminants from insulating oil. By restoring the oil’s dielectric strength (BDV) and maintaining proper viscosity and thermal conductivity, filtration ensures effective insulation and heat dissipation within the transformer.

This process helps reduce insulation ageing, prevents partial discharge and internal arcing, and minimizes the risk of overheating and premature failures. Regular oil filtration supports reliable transformer operation, improves overall efficiency, and significantly extends the service life of both the oil and the transformer.
