Abstract :
A finite-element method for the calculation of the frequency-dependent series impedances of underground power cables is described. These impedances are needed for the analysis of electromagnetic transients in power systems. A technique based on the perturbation concept is used to reduce the size of the solution region inside the poorly conducting earth. The impedances of buried single-core and pipe-type cables are calculated, and the results are compared with those from analytical formulas
