Abstract

The paper presents and discusses results of the study of arc to glow transformation at breaking of DC inductive load of a low power (less than 10 J) and low voltage (about 250 V). The ratio in duration of arcing and glowing is investigated in dependence on circuit parameters, gas quenching medium and its pressure and in particular on contact material. The transition, to complete the study, was analyzed also by means of fast photography and radiation spectra measurements. On the basis of the results the conclusions on possibility of control of the arc to glow transformation, for practical use in low power contact switching devices, are formulated.
