Abstract

In order to find the relationship between arc duration, contact resistance and bridge energy in electric contacts, a new system for measuring bridge waveforms has been developed. The bridge energy was controlled by heating the contact electrode. The experimental results showed that the arc duration of opening contact is closely related to the bridge energy supplied to its bridge state. This fact suggests that the amount of metallic vapor (initial condition) plays an important role in maintaining the metallic phase arc discharge.
