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. The switching functions on their prototype are CO2-neutral.
Using an automobile engine as an analogy, instead of converting an internal combustion engine to a different fuel system to make it more climate-friendly, we’ve completely redesigned the drive technology. We’ve developed the prototype for a CO2-neutral circuit breaker that works and is cost-effective.
