Transient Analysis of Non-Uniform Windings or Lines with Non-Linear Termination

Mohamed Mostafa Saied


The paper deals with the transient analysis of non-uniform transmission lines and machine windings with non-linear terminations. The proposed time-domain technique is characterized by a relatively small computational burden. The analytical solution of the derived system of simultaneous differential and algebraic equations is done in Mathematica. The procedure is applied to several representative case studies involving line and winding non-uniformity and/or the non-linearity of the load termination, such as diodes and saturated coils. Step-function and 50-Hz sinusoidal voltage sources are considered. The results include, among others, the time response of the source and load currents, as well as the current and voltage distributions.
