Abstract:

This paper presents and discusses results of investigations of arc to glow transformation phenomenon at contact opening, under dc inductive loads of low power (= 10 J) and low voltage (= 250 V). The proportion in duration of arcing and glowing is investigated in dependence on current and voltage value, contact material properties, gas quenching medium and its pressure. The transition phenomenon is analysed by means of fast photography and emission spectroscopy. On the basis of investigated results the conclusions about the possibility of control of the arc to glow transformation for practical use in electrical control switching devices are formulated.
