Blitzphänomene im österreichischen Hoch- und Höchstspannungsnetz - transient erfasst

In the last years transient measurements at several substations in the Austrian transmission system have been performed. Based on these measurements it was possible to detect signal sequences which correlate with direct and nearby lightning discharges as well as the coupling effect to phases after lightning strikes to the ground wire. These transient voltages were measured by using resistive-capacitive voltage dividers (RC-divider) to generate a high quality dataset. The high bandwidth of the RC-divider and its resulting frequency stability is needed to analyze such transient events. A correlation between the measurements and the data of the Austrian Lightning Detection and Information System (ALDIS) was performed. In this paper, three different representative measurements of transients caused by atmospheric discharges to or close to transmission lines will be presented.
