In a d.c. machine stray loss is the sum of

WebStray Losses in DC Machine Stray losses are miscellaneous losses which are difficult to determine. The various reasons of the stray losses in DC machine are short circuit current undergoing commutation,distortion of flux etc. The stray losses in DC machine are about 1 % of the total losses. Related Posts WebStray Loss In practical transformer, a fraction of the total flux follows a path through air and this flux is called leakage flux. This leakage flux produces eddy currents in the conducting or metallic parts like tank of the transformer. These eddy currents cause power loss, which is known as stray loss. Dielectric Loss
