The impact of SF6 upon power switchgear technology. II. Switch systems implications

For pt. I see ibid., vol.4, no.5, p.215 (1990). A successful circuit breaker needs not only a suitable interrupter design but also a suitable medium in which to form and quench the arc. SF₆ is increasingly being used in circuit breakers as an alternative to oil and air. The author looks at the impact of SF₆ on switching systems including transmission switchgear and distribution switchgear. The effects on monitoring and control are also discussed
