Although arcs that have large current such as 1 to 100kA at circuit breakers have been investigated many times so far, small currents of arcs have been investigated only a few times. It is important to know a duration time of the small current arc such as a secondary arc on transmission lines in order to maintain power system stability. There are many factors which govern the probability of the small current arc extinction. Characteristics of small current arcs extinction have been studied by an experiment on a analog simulator. Particularly, the duration time and an electric power of the arc have been investigated in this research. From the experiment, it is clear that the duration time of arc is affected by the gap length between the electrodes and a glass along the electrode.
