Abstract (in Japanese) (See Japanese page) 
(in English) Direct currents from 0.5A to 5A in an inductive circuit were interrupted by opening carbon contacts; and the arc duration was measured. Source voltage was 60V, 30V, and 10V; circuit inductance was about 100mH, 50mH, 10mH, and 5mH. In addition, the arc duration was calculated by taking into account the carbon arc V-I characteristics which the author formulated and proposed in 2005. The calculated arc durations turned out to be a close approximation to the measured ones.
