A 3-PHASE MODEL FOR SURGE DISTRIBUTION STUDIES IN ELECTRICAL MACHINES

This paper describes a computer model for surge distribution studies i n the winding of electrical machines. The computer model takes the coi l as the basis for the analysis and uses multiconductor transmission l ine theory to obtain the transference matrix for the winding. Several practical formulations based characteristics are used for parameters. Flux penetration into the iron care and mutual coupling between coils in different phase windings are incorporated into the analysis. The mo del was validated by a comparison of predicted and calculated results in a high voltage motor.
