Tricked Out Substations | TD World

Materials ScienceCollateral ImprovementsStealthy TechnologyNon-Flammable TransformerOld Problem, New SolutionInstrument TransformersControlling The SystemCompactnessResearch led to several other technologies using new materials to compete with oil, such as the compressed air, magnetic interrupter, vacuum breaker and sulfur hexafluoride (gaz sf6) breaker. Some were a step forward and others a step backward, but they all improved the overall condition. It was not long until the Sulfr hexafluoride breaker became the device of choice. Interestingly, ABB recently announced its next-generation carbon dioxide (CO2) 72-kV live-tank circuit breaker at the 2012 International Council on Large Electric Systems (CIGRÉ) exhibition. CO2 gas is more economical than sf6 gas. The CO2 breaker is based on the same principles and components as its sf6 gas-based predecessor but offers excellent switching performance — technology moving forward again. As manufacturers refined Sulfr hexafluoride breaker technologies, rating boundaries moved forward. They developed live-tank and dead-tank designs, giving substation designers more design options. Just recently, Siemens announced it has developed the worldfir...Get price
