TOWARDS THE GREEN WAY
Although several years ago, the European Commission banned the use of SF₆ gas in almost all sectors, only in switchgear industry it is still being used in a big way owing to the advantage that the gas ensures that any arcs that may occur during switching are quickly extinguished. However, the environmental impact of SF₆ gas is around 23,500 times more than that of CO₂ and once leaked it can remain in the atmosphere for up to 3,200 years. Thus, introduction of SF₆ alternatives should be given topmost priority today… - P. K. Chatterjee (PK)
