摘要:
An investigation has been made on the initial separation of high‐current contact electrodes. Three distinct voltage‐time characteristics are observed. Two of these correspond to the formation of a molten‐metal bridge and the third corresponds to an abrupt transition from metallic contact to an arc. Two ideal cases are analyzed theoretically from which a model is developed. The model is then related to the three voltage‐time characteristics observed.
