Transformer Oil Filtration Services in India

About Our Transformer Oil Filtration Service

Transformer oil (insulating mineral oil) absorbs moisture and oxidises over time, reducing its dielectric strength and accelerating insulation breakdown. Ram Engineering's transformer oil filtration service uses high-vacuum dehydration to remove moisture and dissolved gases, restoring BDV to safe operating levels and extending transformer life.
