An Air Drying System is a specialized setup used in the maintenance of electrical transformers to remove moisture and other contaminants from transformer oil. This system operates by circulating dry, filtered air through the transformer oil, facilitating the evaporation and removal of moisture. The process begins with heating the oil to reduce its viscosity, allowing for more efficient moisture extraction. The dry air, often heated to enhance its moisture-carrying capacity, is introduced into the system where it absorbs the water content from the oil. This moisture-laden air is then expelled from the system, leaving behind purified oil with significantly reduced moisture levels. By effectively drying out the transformer, the Air Drying System ensures that the oil maintains its insulating and cooling properties, thereby enhancing the transformer’s performance and longevity.
