As an expression of tungsten arc V-I characteristics, there is Holm’s arc V-I diagram. This diagram is applicable to tungsten arc ranging from 0.05 to 1 mm in gap length and from 1 to 3 A in arc current. However, when calculating opening contact arc in inductive circuit, we sometimes need V-I characteristics of arc longer than 1mm and lower than 1A in current. In addition, the minimum arc current 1 A, determined in Holm’s diagram as the lowest limit of arc current, does not agree with observation. Therefore, we measured V-I characteristics of tungsten arc in the gap range up to 10 mm and the current range lower than 1A, by using opening electrodes. We also investigated the arc extinction V-I characteristics in the low current range where the arc becomes unstable. |
