title: Recent Advances in Vacuum Circuit Breakers
abstract: The paper studies the basic elements of vacuum arc formation and interruption, the design and applications of vacuum switch technology as well as its limitations. Beginning with the description of the main components of a vacuum circuit breaker (VCB), the study moves on to its historical development throughout the years. The context analyzed next refers to the properties and the principles of electrical breakdown mechanisms in vacuum, based on Paschen's law and Townsend theory. The creation of t
