Hi, I'm just starting out as an Electrical engineer and I would like to ask if anyone has any experience with Vacuum circuit breakers used for inductive load (e.g. shunt reactors) switching purposes. I'm trying to do a comparison between Gas-Insulated (e.g. SF6) and vacuum for this kind of application. The reactors are in the range of 22kV, 50-100MVAr.
Technically speaking, both types of circuit breakers seem to be able to meet the required breaking specification, but I cannot help wondering if the vacuum breakers are stable for this kind of application.

I would not think there would be much of a difference if any? Speaking from an environmental standpoint, SF-6 gas is something that really deteriorates the earth's ozone layer
