New Improvements in Transmission Switching Using SF6 ...· PDF filetechnology, for load break switch applications, were circuit switchers. Circuit switchers and devices within this family (see fig. 3) are in series with the disconnect switch and therefore, always in the current path. Consequently, the interrupter contact structure must be far more massive to carry the full rated continuous current.
