| Abstract(in English) | On copper electrical contacts with flat and sphere shape, the breaking arc occurring between electrical contact pair in resistive circuit of DC42V/10.5A were observed with a high-speed camera (1000 frames/s). Both Arc voltage and arc current were also measured simultaneously. By analyzing cathode and anode bright spots in the photographs, the position of cathode and anode spots on contact surfaces were measured. As the result, we were able to confirm that there were some features in the behavior of the arc bright spot by the difference of the shape of contact surface, and some common behaviors. |
