Key Benefits. g³ is a fully type tested gas mixture that provides the same technical performance as SF 6, SF6 while reducing the environmental impact. Applied to HV Switchgear, the g³ gas Global Warming Potential (GWP) is reduced by more than 99%. In other words, the residual gas GWP is less than 1% of that of SF6 SF6.

2018/11/26The light curtain is placed between the hipot tester or the DUT and the operator. An operator touching the high voltage would have to pass through the light curtain, hence opening the interlock, which terminates the high voltage. Of course, if the hipot sits behind the light curtain there must be a way to start the test.
