Abstract :
Mayr-type arc equations were applied to the analysis of high frequency arc extinctions in SF/sub 6/ gas blast circuit breakers. Parameters for the arc equations were obtained from the measured waveforms of high frequency arc conductance. They were calculated in combination with circuit equations. The results gave a good explanation of the measured results. There are a number of examples of applying Mayr-type arc equations to one current zero point in short circuit current interruption. Such equations were applied to high frequency current arc extinctions involving several current zero points, and the results are presented.<>
