Jain, Technology Department, EMCO Limited, Thane India INTRODUCTION The stray losses in a transformer comprise winding stray losses, viz. eddy loss and circulating current loss; the loss in the edge stack (smallest packet of the core limb); and the loss in structural parts, viz. frame, flitch plate and tank. Core loss at the impedance voltage being insignificantly low, is not considered in the present analysis. In case of large generator transformers, stray losses due to high current carrying leads also become significant.
