Lightning induced voltage calculation in lossy transmission lines

This paper describes the implementation of the Rusck's theory of lightning induced voltages on transmission lines in the Electromagnetic Transients Program (EMTP). After summarizing the theory, the paper presents aspects of the implementation such as interfacing problems between Rusck's model and the EMTP. The paper also presents a study on the influence of losses in transmission lines using, as an example, waveforms of actual measured induced voltages in a distribution line.
