The overstrain of tubes by internal pressure
WebbAbstract: The traditional methods for measuring internal pressure P of vacuum tubes of breakers are the magnetron and power frequency voltage withstand test. A magnet coil is needed by magnetron and only very bad tubes can be picked out by voltage withstand test.
