Abstract
SF_6 gas has been increasingly used as the insulating and arc-suppressing medium in switchgears which are used as the protection devices of power system. Nowadays, with these trends, SF_6 load break switches have rapidly substituted for the air or oil-type load break switches, in order to get higher reliability. And, the national standard was made for reliability assessment of SF_6 gas load break switch and testing facilities was also set in KERI(Korea Electrotechnology Research Institute ). This paper introduces the synopsis for the reliability assessment requirements specified in the standard and the assessment results.
