  • Gas insulated power transformers: A growing technology

    Gas is used as an insulating and cooling agent in gas insulated transformers. Sulphur hexafluoride (SF 6) is the main gas used in these types of transformer at present although other gases are under development. The main advantage of gas insulated transformers is that they are environmentally friendly and can be recycled easily.

  • Types and Construction of Power and Distribution Transformers

    Dry-type transformers operate in air or gas rather than being liquid filled. Just like with liquid transformers, the air or gas serves as an insulating medium and also to dissipate heat from the windings. The two general types of construction are the open or ventilated dry-type transformer and the sealed or closed-tank type.
