Abstract

In performance analysis of transmission lines facing lightning, it is extremely important the study of voltages induced by indirect discharges because they occur frequently. The voltages induced by such discharges, can reach high amplitudes, that requires more attention to this phenomenon. The induced voltages can cause shutdowns of the network and even damage the equipment connected to it. As an alternative to analysis of the induced voltage by indirect discharges, this paper proposes the computational modeling of the phenomenon, based on the methodology developed by Sune Rusck, which is highly regarded and used for this type of study. The environment used will be EMTP/ATPDraw, which is public domain, besides being widely used as reference in studies of electromagnetic transients in power systems. From computer simulations, induced voltages are obtained, and presented the analyzes of the influence of some parameters in its amplitude and waveform.
