This paper presents an alternative method for transmission line transient simulation. First, a general theory for the multiphase case is presented in which lumped terminal constraints are incorporated into the Laplace solution of the multiconductor transmission line. The partial fraction expansion method is used to find analytical time-domain waveforms by inverse Laplace transformation. The line model is simple to implement and computational time is short compared to other methods. It takes into account initial conditions and sudden changes in the network configuration. Transient responses of lossy untransposed transmission lines are simulated and the results are compared with EMTPs
