Further as the capacity of the transformer increases, the increased losses demands a higher dissipating area of the tank or a bigger sized tank. This calls for more space, more volume of oil and increases the cost and transportation problems. To overcome these difficulties, the dissipating area is DESIGN OF TRANSFORMERFurther as the capacity of the transformer increases, the increased losses demands a higher dissipating area of the tank or a bigger sized tank. This calls for more space, more volume of oil and increases the cost and transportation problems. To overcome these difficulties, the dissipating area is Despite design precautionsin oil-insulated transformers are primarily related to arcing between parts inside the transformer tank that are at different electric poten-tials. Such a failure event causes a rapid formation of gas and, as the volume of gas builds up, the pressure inside the tank increases significantly. As the metal tank starts to expand, it will deform and
