Abstract

Transient measurements in several substations in the Austrian transmission system were performed in the last years. Based on these measurements it was possible to detect signal sequences which show direct and nearby lightning discharges as well as the coupling effects between phases and ground wire after lightning strikes. 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 analyzed such transient events. A correlation between the measurements and the data of the Austrian Lightning Location System was performed. In this paper, three different representative measurements of atmospheric discharges to or close to transmission lines will be presented.
