Abstract

A method is described for estimating the characteristics of pulses which were destroying transient voltage suppression (TVS) devices onboard the B-52 bomber aircraft. The method relies entirely on an analysis of the physical damage done to serviceable TVS devices in the laboratory under controlled conditions. A photographic record was made and then compared to the field-damaged and laboratory-damaged devices. If the physical appearances of the TVS devices damaged in the lab and in the field were identical, it was thought most likely that they were damaged by approximately the same type of pulse
