During small capacitive current interruption (up to 10A at a voltage up to 175kV) with an airbreak disconnector in a laboratory the arc is recorded using a high-speed camera. Based on recorded data, a general overview of the arc images in different situations and stages is presented. The arc image characteristics and its behaviour are studied. The results show: (i) the arc re-ignites each half cycle of current; (ii) its brightness strongly increases on re-ignition and (iii) is also influenced by the arc current. The residual ionization in the air gap after the arc extinction temporary affects the interruptions.
