Abstract
A limiter includes a housing having a number of gas ports, a number of gas vents and a number of gas channels. Each of the number of gas channels is between a corresponding one of the number of gas ports and a corresponding one of the number of gas vents. The limiter also includes a number of first terminals, a number of second terminals, and a number of limiter devices. Each of the number of limiter devices is electrically connected between a corresponding one of the number of first terminals and a corresponding one of the number of second terminals. Each of the number of gas ports is structured to receive a corresponding ionized gas flow for passage through a corresponding one of the number of gas channels to the corresponding one of the number of gas vents.
