SF6-alternatives testing

In 2006 PGE chose to evaluate dry air/vacuum technology as an alternative to SF 6 by first testing the technology in an inexpensive DTCB application. 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.

    Sulfur hexafluoride (SF6) shows excellent insulation performance as an insulating gas. It is suitable for various climate conditions due to its low boiling point (minus;64 deg;C). Therefore, it has been widely used in power grid equipment. However, its global warming potential (GWP) is 23,500 times higher than that of CO2. Thus, it is imperative to find an environmentally friendly insulating
