This report documents development work for the Repetitive Series Interrupter, a hydrogen thyratron modified for opening switch operation. Fault current interruption is provided by the magnetically controlled interaction of a hydrogen discharge with a wall surface in a suitably constructed interaction channel. Investigations herein reported measure the effects on interruption of regular and irregular wall surfaces as well as of the tube parameters of pressure and channel length, diameter, and geometry. Successful interruptions of 15 kV, 300 ampere fault pulses have been obtained in various chuted channel geometries using an effective magnetic field energy of 5 joules. Optical observation of the discharge column and a theoretical analysis of the positive column under crossed field conditions have been performed. Author
