Abstract :
IN THE PAST, the mathematical analysis of transient oscillations in transformer windings has been based upon a single winding having self and mutual inductances between its turns, capacitances along the stack and to ground, and, in one instance, resistances representing the losses. Such a circuit ignores the presence of secondary circuits, but strangely enough proves adequate to describe the internal high frequency transients of the winding under consideration, not only qualitatively but quantitatively as well. Cathode ray oscillograms, however, do show some difference in the characteristics of the oscillations, depending upon the terminal connections of the secondary circuit.
