Recent Trend of Vacuum Circuit Breakers
Journal of the Vacuum Society of Japan, 2009 The recent trend in the development and the application of Vacuum Circuit Breakers (VCBs) as an environmental friendly equipment for electric power transmission and distribution is described. Using VCB's for circuit breakers and switchgear and extending the range of application of VCB's lead to reduce the usage of SF6 gas, whose global warming ...
