Medium-voltage systems and applications

In power generation, sustainability and digitalization plays an increasingly important part, and climate-neutral and digital power distribution is becoming more and more significant. An essential aspect in this context is energy saving as well as monitoring and control of the increasingly distributed power grid, which is now possible and future-proof thanks to the digitalization of switchgear.

With the environmentally friendly, future-proof switchgear NXPLUS C 24 and 8DJH 24, the blue GIS portfolio is expanded by the 24 kV voltage level. These switchgear types combine the sustainability of the blue GIS portfolio, which comes without fluorinated gases, with the proven advantages of Siemens gas-insulated switchgear. Every GIS of this portfolio is equipped with Clean Air and the proven Siemens vacuum technology.

The NXPower Monitor app from Siemens provides support the digitalization of power distribution and enables efficient controling and monitoring of the current state. NXPower Monitor enables you anytime from anywhere in the world through different views to visualize and monitor electrical assets within a substation or substations across multiple locations. Through different provided views you can realize OPEX savings, CAPEX deferments and leverage optimization potentials in energy consumptions.

The SION 3AE5 is an integral part of the air-insulated medium-voltage switchgear NXAIR. SION 3AE5 vacuum circuit breakers are suited for all standard switching applications in medium-voltage power distribution and industrial networks: from switching load and short-circuit currents to connecting network or busbar sections. Their compact structure, with minimal depth and width dimensions, helps reduce the variety of panels needed. The wide range of panel versions also makes planning easier. 

To guarantee efficient and safe power distribution, it is key that medium-voltage switchgears in power networks operate in a highly reliable manner and comply with the performance requirements – despite age and wear. Our worldwide customer-focused Siemens service centers offer all services needed to keep your medium-voltage switchgears functioning and up-to-date.
