WebIn the full-load loss, this loss is about 10% – 20%. #7. Stray Losses: These are mixed types of losses and there are factors to consider in this loss. Distortion of flow due to armature reaction The short circuit inside the coil. Due to the AD current inside the conductor, there is an excess copper loss. 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
