What is dielectric oil used for?
Dielectric oil is used in electrical transformers and other electrical equipment to insulate and cool components. It serves as a barrier to electrical conductivity, preventing short circuits and electrical failures by maintaining electrical insulation between conductive parts.
Additionally, dielectric oil helps dissipate heat generated by electrical components, improving equipment efficiency and longevity.
What is a dielectric fluid?
A dielectric fluid is a non-conductive liquid used in electrical systems to provide insulation and cooling. It prevents electrical currents from leaking between conductive parts, thereby protecting the system from electrical faults.
Dielectric fluids are used in a variety of applications, including transformers, capacitors and circuit breakers, where they help maintain electrical insulation and manage heat.
How does oil transformer work?
An oil-filled transformer operates by using dielectric oil to insulate and cool internal components. The transformer consists of a core and windings immersed in oil. When electric current passes through the windings, the oil absorbs and dissipates the heat generated.
The oil also provides electrical insulation between the windings and the transformer housing, ensuring safe and efficient operation. The heat dissipated by the oil helps maintain optimal operating temperatures and extend the life of the transformer.
PCBs in oil refer to polychlorinated biphenyls, which are chemical compounds historically used as dielectric fluids in electrical equipment due to their insulating properties. However, PCBs have been phased out and banned in many countries due to their environmental and health risks.
They can cause serious ecological damage and health problems if they leak or are disposed of improperly. Modern transformers and electrical equipment use less harmful alternative dielectric fluids.
