On the impedance realizing ability of minimal two-element-kind networks

Tarnai, Ernest John January 1973 (has links)
The impedance realizing ability of minimal two-element kind networks is considered. As a preamble, a comprehensive survey of relevant mathematics and existing results is presented. An argument based on group theory is used to demonstrate the complex nature of the solution for non-canonic networks. The modal matrix of normal co-ordinate transformation on the cut set admittance matrix is interpreted geometrically as a set of vectors satisfying certain conditions, imposed by the topology and the parameters of the input function of the network, in two Euclidean vector spaces. The existence of the modal matrix, hence the existence of these vectors, is the necessary and sufficient condition for physical realizability. Explicit formulas are developed for third order networks and numerical algorithms for the fourth order networks. A necessary condition is given on the parameters of Z(s) for realizability for networks containing a linear tree of one kind of element. / Applied Science, Faculty of / Electrical and Computer Engineering, Department of / Graduate

Impedance calculation of cables using subdivisions of the cable conductors

Abledu, Kodzo Obed January 1979 (has links)
The impedances of cables are some of the parameters needed for various studies in cable systems. In this work, the impedances of cables are calculated using the subdivisions of the conductors (including ground) in the system. Use is also made of analytically derived ground return formulae to speed up the calculations. The impedances of most linear materials are calculated with a good degree of accuracy but materials with highly nonlinear properties, like steel pipes, give large deviations in the results when they are represented by the linear model used. The method is used to study a test case of induced sheath currents in bonded sheaths and it gives very good results when compared with the measured values. / Applied Science, Faculty of / Electrical and Computer Engineering, Department of / Unknown
