IEEE Transactions on Power Apparatus and Systems, 1972
The effectiveness of the commutation principle, using vacuum interrupters as a means for interrupting high direct current at high voltage, has been demonstrated convincingly by a large number of tests. Currents in excess of 15 kA at 20 kV have been interrupted by a single device in an inductive circuit.

2008 23rd International Symposium on Discharges and Electrical Insulation in Vacuum, 2008
The results of switching tests of a DC vacuum circuit-breaker designed for rated voltage 3.3 kV and rated current 3000A are presented. The circuit-breaker is intended for current interruption in the networks with fault currents up to 30 kA. To interrupt the direct current, the authors used a method of artificial current transition through zero in the ...

Vacuum-state estimation of vacuum circuit breakers
SPIE Proceedings, 1994The vacuum state of vacuum switching elements after production is checked normally by Penning- or Magnetron methods (combined electrical and magnetic field). Vacuum in the range of 10-1 - 10-4 Pa can be measured in this way. After assembly into circuit breakers however, these methods are not applicable.

High voltage vacuum circuit breakers
IEEE Transactions on Power Apparatus and Systems, 1975A new line of high voltage vacuum power circuit breakers is being developed for 121 kV and above and will use the new vacuum interrupter module presented in a companion paper3. The first ratings in production will be 242 kV with interrupting capabilities of 40,000 amperes, followed by breakers rated 50,000 amperes; both of these will have continuous ...
