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)

With the pace of government initiatives for development of smart grid, there is need to develop different kinds of switchgear suitable for smart grid operation and that is more compact, reliable, environment friendly and requires minimum installation and commissioning time. By Ashok Upadhyay

Due to the continuous increase of power handling capacity, increase in network voltages, continuous design improvements and operational requirements of switchgear. In this article, short circuit test duty requirements of 12kV circuit breaker are discussed. By Yugal Agrawal

The smart grid is a self-healing network equipped with dynamic optimization techniques that use real-time measurements to minimize network losses, maintain voltage levels, increase reliability, and improve asset management...

Given their critical role in substation automation, the scope of switchgear is also expected to grow considerably in the near future. Given the government’s reform initiatives, the switchgear market is likely to continue on its growth trajectory.

Many unwanted disturbances or fluctuations in voltage or current of electric circuits take place due to many known or controlled and unknown or uncontrolled reasons – like sparking, high voltage, moisture, leakage, over loading etc. Thus, use of appropriate switchgears protect us from harmful damages... - Dr S S Verma
