Blue GIS by Siemens a breakthrough 🌏

  • Environmental awareness and resource efficiency require new technologies. To minimize the emission of fluorinated gases (F-gases), Siemens has developed innovative solutions using alternative technologies that enable the F-Gas-free, easy, and secure transmission of electrical power.
  • 100% sustainable performance, Working towards a sustainable future calls for innovative, environmentally friendly, and digital solutions for the medium-voltage power supply. Get ready to make a difference with blue GIS.
  • The “Clean Air” technology stands for ecological, future-proof power distribution and easy handling throughout the entire lifecycle. It combines the sustainability of the “blue GIS” portfolio with the well-known advantages of the 8DJH product family that have been proven in practice for a long time.
  • The result: Real innovation, which turns over a new, pathbreaking leaf in the area of load-break switchgear.
  • BLUE SWITCH
  • Blue GIS by Siemens is a gas-insulated switchgear product that uses clean air as an insulation and interrupting medium instead of sulfur hexafluoride (SF6) or other fluorinated gases. SF6 is a greenhouse gas that has a high global warming potential and is harmful to the environment. Blue GIS by Siemens is an environmentally friendly, technically advanced and resilient solution for medium-voltage power distribution.
  • The centerpiece of the switchgear is the innovative “blue Switch”, a three-position switch-disconnector with vacuum interrupter in the secondary path, which does not produce any toxic decomposition products during the switching process. Thus, the dielectric strength of the gas remains constant throughout the entire service life, ensuring environmentally friendly disposal of the switchgear at the end of the lifecycle. The blue Switch is used in ring-main panels and in combination with fuses in transformer panels. The simple, reliable and well-known operating principle close, open, earth of the 8DJH product family is carried on within the blue GIS portfolio, and therefore ensures continuity.

Applications or use Cases of Blue GIS by Siemens

  • Power transmission and distribution: Blue GIS by Siemens can be used for power transmission and distribution at different voltage levels, such as 8 kV, 145 kV and 420 kV. Blue GIS by Siemens can provide reliable and resilient power supply for various sectors, such as industry, infrastructure and renewable energy.
  • Seismic qualification: Blue GIS by Siemens can withstand seismic activities and harsh environmental conditions without sustaining any damage or impaired functionality. Blue GIS by Siemens has successfully passed seismic qualification shake-table tests in line with IEEE 693 high level specifications. This can ensure grid resilience and safety for regions with high seismic risk.
  • Wireless power substation: Blue GIS by Siemens can be integrated with wireless technologies such as 5G, LTE and Wi-Fi to connect various devices and systems in substations, such as protection relays, circuit breakers, transformers and meters. Wireless connectivity can provide large bandwidth, wide coverage, low latency and high security for data transmission and control. This can enable remote monitoring and control, smart metering, asset management and cybersecurity for substations.
  • Image Attachment

Some benefits of using Blue GIS by Siemens are:

  • Zero global warming potential: Blue GIS by Siemens uses compressed synthetic air, which consists exclusively of natural components from ambient air, as an insulation and interrupting medium. This eliminates the use of SF6 or other F-gases, which have a very high global warming potential and contribute to climate change.
  • High performance and reliability: Blue GIS by Siemens uses proven vacuum interrupter technology to achieve very reliable and long-term stable power switching functionality. Blue GIS by Siemens can also withstand seismic activities and harsh environmental conditions without sustaining any damage or impaired functionality.
  • Compact design and low lifecycle costs: Blue GIS by Siemens has the same compact dimensions as the variant with SF6, but with a lower weight and a smaller footprint. Blue GIS by Siemens also has lower maintenance and operating costs, as it does not require any gas handling or refilling.
  • Digitalization and smart grid readiness: Blue GIS by Siemens can be integrated with digital applications and Internet of Things (IoT) systems for smart and sustainable power distribution. Blue GIS by Siemens has integrated sensors and communication interfaces to higher-level automation and IoT systems.

Some challenges of using Blue GIS by Siemens are:

  • High investment: Blue GIS by Siemens requires significant capital expenditure to deploy and maintain, which may not be affordable or feasible for some power utilities .
  • Technical complexity: Blue GIS by Siemens involves sophisticated technologies that require high-level skills and expertise to operate and manage, which may not be readily available or accessible for some power utilities .
  • Regulatory uncertainty: Blue GIS by Siemens may face regulatory barriers or uncertainties regarding data privacy, cybersecurity, interoperability and standardization, which may hinder its adoption or innovation.
