Abstract : In their use, valve-type divertors are subject to the effect of overloads with various wavefront durations. During a thunderstorm the prediversion time varies from fractions of a microsecond to tens of microseconds, while with commutation overloads it is up to hundreds and thousands of microseconds. The equivalent circuit of the divertor is complex; therefore its volt-second characteristic has a peculiar nature. In the range of prediversion times of approximately 3-10 microseconds the breakdown voltages of the divertors ordinarily have a minimum value; with a decrease in the prediversion time relative to the indicated range the breakdown voltage of the divertor sharply increases, while with an increase in the prediversion time it smoothly increases, attempting to reach a certain limit. This article examines divertor breakdown voltages measured on beveled waves.
