Why is an oil filled transformer used?

An oil transformer is mainly used for its excellent insulation and cooling properties. The oil inside the transformer serves as both an electrical insulator and a coolant. The oil’s insulating properties prevent arcing and breakdowns between transformer components, while its cooling function helps dissipate heat generated during operation.

Oil transformers are often used in high voltage applications where efficient heat dissipation and reliable insulation are essential.

Why does a transformer need oil?

The use of an oil filled transformer extends to several applications where reliable performance and high voltage handling are required.

These transformers are commonly used in power distribution networks to step down high transmission voltages to levels suitable for local distribution. They are also used in industrial environments to provide stable power to large machines and in substations where robust insulation and cooling are required to handle high electrical loads.

Why oil in a transformer?

Transformer oil is used in several key areas of electrical transformers. It functions as an insulating medium, providing a barrier between high voltage components to prevent electrical failure.

Additionally, transformer oil is used as a coolant to absorb and dissipate heat generated by electrical currents inside the transformer.

Oil circulates through the transformer, carrying heat away from the core and windings to maintain optimal operating temperatures.

A dry type transformer is used when fire safety and environmental concerns are paramount.

Unlike oil-filled transformers, dry-type transformers do not use liquid insulation, which eliminates the risk of oil leakage and reduces the risk of fire. They are commonly used in interior applications including commercial buildings, data centers and high-rise structures. Dry-type transformers are also preferred in areas with strict fire safety regulations or where environmental conditions make oil-filled transformers unsuitable.

Hermetic type transformers are used in applications where environmental protection and maintenance-free operation are important.

These transformers are sealed to prevent moisture and contaminants from entering, which helps protect internal components and extend the life of the transformer. Hermetic transformers are often used in harsh or remote environments where exposure to the elements or the need for frequent maintenance is an issue.

They are suitable for use in industrial environments, outdoor installations and locations where reliability and minimal maintenance are essential.
