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

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 article sheds light on various intricacies of hybrid HVDC Circuit Breaker.
In-depth analysis on how digitisation helps in improving performance and reliability of switchgears. By Subhajit Roy, Group Editor
WAGO offers uninterruptible power supplies (UPS), buffer modules, redundancy modules and a wide range of electronic circuit breakers (ECBs) as a complete system for seamless upgrades…
The global market is set to witness a significant growth due to the continued growth of construction and developmental activities, increasing access to electricity, and growth of renewable power generation projects…
The selection of over-current protection devices such as fuses and circuit breakers is made more complicated when high inrush currents must be tolerated. The over-current protection must react quickly to overload or short circuit faults but must not interrupt the circuit when the (usually harmless) inrush current flows…
As a global technology leader in power management solutions and with a host of new technologies and solutions, Eaton is responding to some of the most critical electrical power management challenges that the country faces today.
Timing measurements on gas-insulated switchgear (GIS) with grounding on both sides.
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.
Retrofitting old medium voltage switchgear with newer technology is an efficient, cost effective and economical option for preserving existing assets, thus, saving cost and time. In the race of implementation and adaptation of new technology we just destroy existing installation by scraping the products for want of alternate solutions and technologically sound and reliable supplier… - Paresh Shah, N P Jhaveri
“Circuit breakers are mechanical switching devices, capable of making, carrying and breaking currents under normal circuit conditions – and also making, carrying for a specified time and breaking currents under specified abnormal circuit conditions such as those of a short circuit... - Dr P K Pattanaik
There are attractive possibilities of the combination of SF6 insulation with vacuum interrupters. Another recent suggestion is to use liquid SF6 in a container much like oil… - Prof N S Gorhe
