  • High Voltage Switchgear | Inventors | Siemens Global

    High Voltage Switchgear Circuit breakers are needed to ensure that our energy supply systems run smoothly. Until now, they’ve used gases that are much more harmful to the climate than CO2. Sylvio Kosse and Paul Gregor Nikolic at Siemens Energy are working on a way to use pure air in place of these gases.

  • Switchgear - Wikipedia

    High-voltage switchgear was invented at the end of the 19th century for operating motors and other electric machines. The technology has been improved over time and can now be used with voltages up to 1,100 kV. Typically, switchgear in substations are located on both the high- and low-voltage sides of large power transformers. The switchgear on the low-voltage side of the transformers may be located in a building, with medium-voltage circuit breakers for distribution circuits, along with
