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

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)
