Earthing is carried out to facilitate electromagnetic compatibility between systems and to avoid the occurrence of electrical shock to person working in the vicinity of that electrical system during ground faults. This article presents the need of earthing in control panels. - Neha Mistri

Escalating demand of solar application increased the use of Inverter-duty transformers especially of multi winding type. For design verification, short circuit withstand test is to be conducted on these transformers. This article describes the procedure of short circuit withstand test on multi winding Inverter-duty transformer as per national and international standards (IS, IEC, ANSI/IEEE, etc.) - Yugal Agrawal, K. Sharath Kumar

With the devices getting smarter, user interfaces getting IoT enabled, the surge in intelligent switchgear is the next big trend.

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
