Abstract

This paper describes a technique for calculating interturn voltages in machine windings during transient conditions. The technique is based on the measurement of switching transients at the machine terminals and computer simulation of the surge travelling through the winding. The machine winding is treated as a multiconductor transmission line and the discrete Fourier transform and convolution techniques are used for calculating the switching transient distribution along the winding. Switching transients results obtained on two electrical motors in the Manzanillo II power plant are used in the analysis
