However, the technology moved forward with the vacuum circuit breaker coming to dominate the medium voltage arena, and the gas circuit breaker (SF6) dominating for the higher voltages to the EHV range. These technologies exhibit a "constant kA" performance, which drove the ANSI/IEEE standards toward this ratings basis in the 1999 revisions.
