Introduction to Oil Immersed Transformers
Oil - immersed transformers are one of the most common types of transformers used in power systems. They use insulating oil as both a coolant and an insulator. The oil helps to transfer heat generated during the operation of the transformer to the cooling surfaces, ensuring that the transformer operates within a safe temperature range. This type of transformer is widely used in various applications, including power generation, transmission, and distribution, due to its high efficiency, reliability, and long service life.
