Cellulose content in form of insulation present in the transformer mainly captures moisture and releases it in oil thereby deteriorating oil parameters. Hence need arises to dry out the transformer using a low heat and high vacuum technique. Vacuum drying ovens find applications in transformer repairing workshops or transformer manufacturing industry. Often dried transformers are filled with oil under vacuum. Thus oil filling stations form integral part of a vacuum drying oven. NACH resolves the ovens to meet distinct designs.
