What is an oil-immersed distribution transformer?

An oil-immersed distribution transformer is a type of transformer where the electrical components are submerged in insulating oil, enhancing cooling and insulation properties. This oil effectively dissipates heat generated during operation, ensuring efficient performance. The insulating properties of the oil prevent electrical arcing and enhance safety. Regular maintenance, including oil cleaning and regeneration, is essential for optimal function, as oil quality can deteriorate over time, sometimes leading to issues like oil ignition transformer concerns if contaminants are present. This type of transformer is widely used due to its reliability and longevity in various electrical applications.
