Turbulence cooling is an important energy removal mechanism for switching arcs. In the present work a two pressure system with an upstream stagnant pressure of up to 10 bar is used to generate low current arcs in a converging-diverging nozzle to obtain experimental results for the verification of turbulence models. Arc voltage and current measurement is taken for transient arcs with a maximum length of 60 mm in the current range of 100 A to 333 A. The repeatability of the results is discussed.
