  • Abstract
    An SF6 circuit-breaker which uses the principle of autoexpansion, a combination of rotary arc and self-pressurization principles, is discussed. The operating principles and the design considerations involved in this interruption technique are examined. The principal performance features are given, particularly in comparison with existing SF6 techniques. Details of the research techniques and diagnostic systems that have facilitated the design and development of this circuit-breaker are given
