Abstract: Electromagnetic transients in arbitrary single- or multiphase networks are solved by a nodal admittance matrix method. The formulation is based on the method of characteristics for distributed parameters and the trapezoidal rule of integration for lumped parameters. Optimally ordered triangular factorization with sparsity techniques is used in the solution. Examples and programming details illustrate the practicality of the method.

TL;DR: In this technique, large networks are split into smaller ‘subsystems’ by using the natural propagation delay introduced by transmission lines, which yields computational results perfectly in agreement with the traditional non-split simulations.

Wave propagation in overhead wires with ground return
TL;DR: The problem of wave propagation along a transmission system composed of an overhead wire parallel to the (plane) surface of the earth, in spite of its great technical importance, does not appear to have been satisfactorily solved.

TL;DR: With this method, direct solutions are computed from sparse matrix factors instead of from a full inverse matrix, thereby gaining a significant advantage in speed, computer memory requirements, and reduced round-off error.

Transient analysis of lossless transmission lines

TL;DR: The method of characteristics provides a simple analytic solution for the transient analysis of a uniform, lossless transmission line that is superior in both speed and accuracy to the familiar method of integrating the differential equations that describe a lumped LC model of the line.

TL;DR: The influence of the computer not only on the modus operandi of circuit design, but also on network theory itself, is discussed and a new approach to ac analysis, using the mixed method and a numerical solution of the matrix eigenvalue problem is described.
