| Abstract(in English) | The relationship between the condition of contact surfaces and the motion of arc spots are investigated in DC 42V/10A resistive circuit using a microscope and a high-speed camera for Ag electrical contacts. Surface conditions of electrical contacts are observed with the microscope after each breaking operation. As results, the diameters of the cathode and anode spot regions that are obtained by using a high-speed camera are almost corresponding to photographs of the traces of the erosion by a microscope. And the films on the cathode surface may be generated at different stage of the arc duration. |
