A high-power electric arc, such as that burning in the interrupter (usually a supersonic nozzle) of a gas-blast circuit-breaker, presents a challenging problem both to theoretical and experimental investigators. The complex non-linear nature of the governing equations and steep radial gradients of arc quantities make analytic and numerical solution of the equations extremely difficult. Experimental work is also difficult due to the extreme physical conditions encountered. It is therefore highly desirable to use similarity theory to extend the limited results available to as wide a variety of arcing conditions as possible.
