![]() Nor is there any requirement to report the quantity of gas used in the devices. One result of risk-free handling is that certain precautions are no longer necessary during shipping, installation, maintenance, and recycling. “Our blue portfolio makes it possible to modernize and expand the existing power grids at the highest level of safety and to simultaneously reduce our ecological footprint to an enormous extent without having to compromise on performance and economic feasibility.” Just beware that one smart battery doesnt hold much, so if it is scrolling distance away from the 'music box' then the smart battery could have recharged by the time you scroll over to it. They will keep the charge as long as nothing is draining from them. ![]() This is reflected in our blue portfolio,” say Ralf Christian, CEO of Siemens’ Energy Management Division. The small transformers having power doesnt mean anything. “We’re constantly refining our products with a view to higher efficiency, safety, and environmental compatibility. They offer the usual performance as well as additional, superior features. The new blue circuit-breakers achieve a rated voltage of 145 kV. Siemens has been using this technology in the medium-voltage range up to 72.5 kV for over 40 years. Clean-air is technically prepared and purified air in a mixing ratio of 80 percent nitrogen to 20 percent oxygen. This innovative solution relies on a vacuum interrupter unit for switching and extinguishing the arc and on clean-air for insulation. The switchgear thus require no SF₆ switching and insulating gas. At the Noerdlingen substation, Siemens installed its new 3AV1 blue high-voltage circuit-breakers with vacuum-interruption technology and a combined voltage and current converter, including clean-air insulation, in a 110-kV high-voltage grid for the first time.
