WebNov 23, 2024 · Advantage of this type over others of circuit breakers are: In comparison to other types, it is a superior dielectric medium. Its service life is much longer, compared to other types, and also they need bare minimum maintenance. It is more efficient, very compact, and cost-effective. WebThe dielectric constant of vacuum is nearly the same as that of air, but the breakdown voltage is higher and not dependent on air humidity and particulate pollution. Air capacitors are non-polar. This means that air capacitors may be safely used without regard to DC polarity, which is useful in some applications.
