“…Vacuum interrupter arc control systems have evolved over the past forty years to cover all of the specified fault currents needed for Medium Voltage distribution systems [4]. As has been shown for vacuum switches, the properties of the device are decided almost solely by the selection of the special contact material which dominated the properties of the arc, with the natural diffuse arc mode causing natural interruption at the next available current zero.…”

“…The other part of micro-parts remains connected with the surfaces of electrodes thus representing the micro roughness. It may occur that they contain microspikes, which if acted on by sufficiently strong electric field can initiate emission mechanisms of the breakdown [15][16][17].…”

“…Even though modern vacuum interrupter (VI) technology began in the early 1960's (1,2,3), it is still thought of as a new technology. One reason perhaps is that the development of the VI engendered a whole new area of arc research; so much so that an international conference is held every two years to discuss the latest findings (4).…”

rhis paper will provide application guidelines for, and will show the advantages of, applying vacuum interrupters to switch and to protect power distribution circuits. The performance of vacuum interrupters for load switching and for short circuit interruption will be discussed with reference to long term switching life and low maintenance costs. During this discussion the unique ability of the vacuum interrupter to handle developing faults will be analyzed. The effects of current chop and voltage escalation on the components in a distribution circuit will be examined, and straightforward methods to minimize their effects will be presented. The advantages of using vacuum interrupters for long life, maintenance free performance for capacitor switching and for motor switching will be discussed. The paper will discuss the very fast recovery characteristics of vacuum interrupters, and will show how these characteristics can be used to produce a circuit breaker that will reliably protect distribution transformers. Finally, the use of vacuum interrupters for other switching duties will be examined.
