Observation of Breaking Arcs of Ag or Cu Electrical Contact Pairs with a High-Speed Camera
Summary :
Breaking arcs occurring between Ag or Cu electrical contact pairs in DC 56 V/7 A resistive circuit are observed with a high-speed camera (1000 frames/s). As a result, the increase of brightness of the arc-emitted light synchronizes with the increase of arc current in the latter half of arc duration. For the case of Ag contacts, the brightness increases in entire region of the breaking arc with sudden increase of the arc current. On the other hand, the increase of the intensity for Cu contacts occurs in not only entire discharge region but also anode spot region significantly.
