Abstract

Experimental results on classical long spark development optically studied in July-August, 2002 at the High Voltage Research Center (HVRC), Istra, Russia have been presented. Main goal of these studies was to test universal streak and framing cameras K004M and K008 developed by the BIFO Company, Russia for the University of Florida, USA to be used at the International Center for Lightning Research and Testing (ICLRT) at Camp Blanding, Florida. Both cameras were tested at the conditions (solid angles, spatial and time resolution, sensitivity etc.) being like as much as possible to those expected in actual triggered-lightning experiments at Camp Blanding. Basic results on testing have been found to give hope well enough for the triggered-lightning research. Additionally to the testing, some features of long spark development in different stages have been studied using up to three devices operated synchronously. In combination with two cameras pointed out above, an old analog image converter streak camera of FER14-type (designed in 1980 by the VNIIOFI, Moscow as requested by the All-Union Electrotechnical Institute, Istra) instrumented with a novel CCD readout system SU04-type (designed by the BIFO Company) was being used. This combined system FER14+SU04 has been found to operate well enough too. Some experimental results with pictures presented expand available data and current knowledge on electrical discharge in large air gaps.
