SF6-alternatives leakage for Hitachi

In 2009, the utility purchased a Hitachi 72-kV, 31-kA, 2000-A dry air/vacuum breakers for the pilot at Borden substation outside of Madera CA. This was the first utility HV dry-air vacuum DTCB installation in California. The procurement process included an ISO 9001 quality audit of the Hitachi Ltd. factory and a design review of the breaker.
