Amid growing concerns about its environmental impact, utilities worldwide are seeking to eliminate sulphur hexafluoride gas from their switchgear.

Will these megatrends create a shortage in Medium Voltage Gas-Insulated Switchgear (GIS) and Solid Insulated Switchgear (SIS)?

“Switchgear is a general term covering switching devices and their combination with associated control, measuring, protective and regulative equipment, also assemblies of such devices and equipment with associated interconnections, accessories, enclosures, and supporting structures.” -IEC

Market players must adapt to evolving trends and regulatory changes by investing in advanced technologies.

Together with customers, partners, and other key stakeholders, Hitachi Energy is co-creating pioneering technologies that are accelerating the energy transition toward a sustainable future.

This facility is one of the largest and most efficient power plants in Bangladesh, designed to enhance electricity availability in the Dhaka region, the capital city.

Activities and real-world examples.

Grid distribution systems are updating their planning processes to handle the increasing integration of distributed energy resources.

The earth mesh is a key component in the design and operation of substations. The purpose, function, and design considerations of substation earth meshes are detailed, along with practical examples.

One of the largest distribution grid switchgears in Switzerland is currently being replaced.

As the demand for electricity continues to grow and the grid becomes more complex, the role of mobile substations will likely expand.

The Richland facility manufactures NW breakers, low-voltage switchgear, and switchboards.

Sometimes root cause of downtime is easy to identify – other times it is much more insidious and harder to detect, like partial discharge (PD).

Electrical utilities request automatic shunt reactor switching to enhance power system performance.

The circuit breaker is king of switchgear.

Despite the positive outlook, the market faces challenges such as fluctuating raw material prices.

“For 40 years now, our plant in Frankfurt-Fechenheim has been a global center of competence for gas-insulated medium-voltage switchgear.” -Mark Backhau, Siemens

Mobile substations, which restore power quickly in emergencies, are rising in demand.

Lucy Electric’s Sabre EcoTec uses synthetic air instead of SF6/

New switchgear designs focus on digitalisation of substations.

“We are proud to be the first company in Norway to only use SF6-free switchgear across our grid.” -Vidar Kristoffersen
