The controlled tripping of high-voltage impulse generators

Abstract

This paper summarizes the requirements of tripping circuits and spark gaps which enable a high-voltage impulse generator of one or more stages to be discharged in synchronism with the operation of such measuring equipment as a cathode-ray oscillograph or a rotating-mirror camera. A triggered spark-gap and the associated circuits which give accurate synchronism are described. A tripping pulse of only about 5 kV is required, and this may be obtained from the time sweep circuit of a high-voltage oscillograph, or from a blocking oscillator. Tripping of a single-stage generator is obtainable within 0.1 μsec of a pre-determined short delay time.
