| Research Abstract |
An observation method of electrical contact surfaces and break arcs was proposed using two pairs of a high-speed camera and an optical band pass filter. The formation process of traces on the contact surface was investigated by the relation between the changes of the traces on the contacts and the motion characteristics of the break arcs. As a result of investigation, the periods and times when the traces on the contact surfaces were formed were shown while the break arcs were maintained.
