Remark on the lumped parameter modeling of transmission lines

Transmission fines are distributed parameter systems. Instead of distribute d parameter models, lumped parameter models are also used for steady-state and transient analysis of transmission lines. Lumped parameter modeling for transmission lines is obviously an approximation. This paper aims to inves tigate the theoretical error in the lumped parameter modeling of transmissi on fines for steady-state and transient analysis. To determine the error, s teady-state and transient responses of the transmission line are calculated by using both distributed and lumped parameter modeling. The effect of num ber of sections used for lumped parameter modeling is investigated. Obtaine d results can be used for the determination of the number of sections.
