SF6 GAS INSULATED TRANSFORMER
EMPLOYS SF6 GAS INSTEAD OF THE CONVENTIONAL OIL BOTH AS AN INSULATING AND COOLING AGENT.
SF6 – AN OVERVIEW
SF6 is Sulphur hexafluoride formed by chemical reaction of molten sulphur and fluorine.
It is colourless, odourless, nonflammable, non-corrosive and chemically stable.
High dielectric strength.
Quenches arc effectively and has excellent cooling properties.
Good thermal conductivity and excellent thermal stability.
It’s not poisonous and eco-friendly.
APPLICATIONS OF SF6 GAS INSULATED TRANSFORMER
Hospitals, underground shopping centers, substations where a high level of fire safety is required.
Water treatment plants and hydroelectric power plants where waterways must be kept unpolluted.
Thermal power plants, chemical plants, public works facilities etc where high reliability is required.
CONCLUSION
Incessant research and continuous developments have made construction of large capacity gas insulated transformer possible.
With the eco-friendly aspects of SF6 gas and considering the huge advantages of the gas, long strides can be made in this regard to further utilize it and increase the efficiency of the transformer and making the power system more reliable and safer.
