High Voltage Engineering - SILO.PUB is relevant to point out that, of the gases examined to-dat£, SF$ has probably the most attractive overall dielectric and arc quenching properties for gas insulated high voltage systems. Ideally, vacuum is the best insulator with field strengths up to 10 V/cm, limited only by emissions from the electrode surfaces.[email protected]
