Abstract
Measurements have been performed to determine the heat flow to the cathode during arcing in vacuum. It is shown that for a range of metals the heat flow is proportional to both current and arcing time. Depending on the cathode metal the losses vary from 25 to 34% of the total arc input. A relation between cathode heat loss and arc voltage is established. The experimental results are compared with theoretical calculations as found in literature.Keywords
