Medium-voltage systems

Economical and reliable power distribution
About medium-voltage systems
The primary task of medium-voltage switchgear is economical and reliable power distribution. We take this responsibility seriously and offer products and solutions for medium-voltage systems to our customers around the world. Our optimally coordinated systems meet the growing technical requirements and ensure reliable power distribution – in air-insulated or gas-insulated switchgear, and for applications outdoors or on the ocean floor.Digital switchgear solutions for primary distribution
Gas insulated switchgears are relevant for all applications in MV distribution grids. Changing global trends and needs over the whole vertical business portfolio require the further digitalization of switchgears.
Digital switchgears for intelligent secondary distribution grid automation
Gas insulated switchgears are relevant for all applications in MV distribution grids. Changing global trends and needs over the whole vertical business portfolio require the further digitalization of switchgears.The energy transition, renewable energy infeed and increasing use of electromobility lead to volatile energy flows today’s medium-voltage distribution grids are not designed for. Therefore, there is an increasing request for smart RMU’s, to get further operating and condition data. This presentation will give an overview about the Siemens solution for smart RMU's of the 8DJH family.
Arc fault – Effects mitigation measures in air-insulated medium-voltage switchgear
The occurrence of an internal arc fault in a well-designed, type-tested, correctly installed, and operated switchgear is improbable – but not impossible. Potential consequences of arc flash incidents on medium voltage switchgear and available active measures with their effects on the availability of the electrical equipment will be presented.
