Abstract :
KNOWLEDGE OF THE NATURAL frequencies of air-core and iron-core coils and of transformer and generator windings is of essential theoretical and practical importance. The transient response of coils and windings subjected to impulse waves has been determined in the literature by two different methods, the “standing wave” and the “traveling wave” approach. The values of the natural frequencies enter into the analytical expressions of both these methods of calculation.
