Types of Transformers: Dry Type vs. Oil Filled
Transformers play a crucial role in electrical systems, particularly in medium voltage applications. Among the various types available, dry type and oil filled transformers are two primary categories that serve distinct purposes. Dry type transformers utilize air for cooling and insulation, making them safer for environments where flammable materials may be present. They are also easier to maintain and install due to their compact design.
On the other hand, oil filled transformers use mineral oil as both a coolant and an insulator. This type of transformer is typically more efficient and can handle higher loads. However, they require more careful installation and maintenance to prevent leaks and ensure safety. Depending on the specific application and environment, companies must decide which type of transformer best suits their needs.
