Smart Transient Free Switching of Switchgears
In this article a basic duty of a “Controlled Switching Device” in back to back switching of a shunt capacitor banks has been explained. The Transients developed are very high in nature and are very injurious to the circuit breaker used for this duty.
A case study, highlighting the need for implementing such device for back to back switching of shunt capacitor banks is also described... - Er K K Murty

Load Break Switch: Evaluation of Breaking & Making Capabilities
Among several switching devices largely used in medium voltage distribution systems, which change the grid configuration, isolates faulty parts from the grid, etc. Load break switch is a remarkable one. For the reason to analyse the interrupting capabilities, load break switch rated up to 52kV has to undergo various test duties according to IEC 62271-103. This article focuses on the parameters involved in evaluation of its behaviour during make-break tests. - Yugal Agrawal, K.Sharath kumar

Common Errors While Designing an Electrical Protective Scheme
If the selection of inappropriate specifications switchgears go unnoticed, it may jeopardize safety of man and machines both. Therefore, utmost care is required, while designing an electrical protective scheme as far as selection of CTs of correct specifications, switchgears, etc is concerned.
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)
