A computer model for calculating steep-fronted surge distribution in machine windings

Abstract

A computer model for predicting the distribution of steep-fronted surges in the line-end coils of machine windings is described. The model uses certain aspects of previous models combined to achieve simplification of solution while retaining accuracy. The solution technique is based on multiconductor transmission line theory and modal analysis. Parameter evaluation is based on the relationship between capacitance, inductance and wave velocity. The theory is extended to include a number of series-connected coils. Experimental and computational results are presented to illustrate the application and accuracy of the model.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
