Vegetable insulation oils in transformers have become a reality. However, they are inherently hydrophilic and can absorb much moisture. Existence of moisture in transformer insulation will generally lower the breakdown voltage (BDV) of oil. Moisture will also accelerate cellulose deterioration by in...
