Overview of Oil Immersed Transformers
Oil immersed transformers are widely used in electrical power systems for their efficiency and reliability. These transformers use oil as an insulating and cooling medium, which allows them to operate at higher temperatures without compromising performance. The oil also provides excellent dielectric properties, making these transformers suitable for high-voltage applications.
One of the significant advantages of oil immersed transformers is their ability to dissipate heat effectively. This feature is crucial in preventing overheating, which can lead to transformer failures. Additionally, the oil acts as a barrier against moisture and contaminants, further enhancing the longevity of the transformer.
