Drying Out of Transformer is a critical maintenance procedure aimed at removing moisture from transformer oil. Moisture within the oil can severely impair its insulating properties, leading to reduced dielectric strength and an increased risk of electrical discharges. Additionally, water in the oil accelerates the aging process of both the oil and the transformer’s internal components, promoting corrosion and the formation of acidic byproducts. By effectively drying out the transformer, moisture is eliminated, thereby preserving the oil’s ability to insulate and cool the transformer efficiently. This not only enhances the immediate performance of the transformer by ensuring optimal electrical and thermal conditions but also significantly extends its operational lifespan by preventing premature degradation and mechanical failures.
