Application of image converter camera for investigation of discharges from an artificial cloud of charged water aerosol

摘要

Results of experimental investigations of optical characteristics of discharges from an artificial cloud of charged water aerosol by using the K011miniature 9-frame image converter camera are presented in the paper. Application of high speed image converter camera has allowed clearly distinguished the peculiarities of a final stage of three types of discharges from the charged aerosol clouds. Each type of final stage is differed not only on optical and current characteristics, but the sequence of formation. It was found that the type of final stage depends on character of development the previous leader discharges in the gap "charged aerosol cloud-grounded rod on the plate". The most frequently case is the formation of final stage after development of upward leader from the grounded rod and of counterpart negative downward leader from the charged aerosol cloud boundaries. Simultaneously registered current characteristics have shown significant correlation between optical and current characteristics of final stage of discharge. More powerful discharge luminosity the higher current amplitude and the shorter final stage of discharge.
