Tension de claquage en surtension de manoeuvre d'éclateurs tige-plan de très grands écartements

This report describes the results of test experiments which have allowed us to obtain the shorting voltage at 50% of pin spark gaps, up to a 50 metre spacing, as a time dependence of the applied pulse edge. Based on these results, an empirical formula was developed with which one can calculate the minimum shorting voltage to 50% which would correspond to a critical pulse edge, dependant on the spacing of the pin spark gaps.
