Hysteresis loss

In hysteresis …which is known as the hysteresis loss, in reversing the magnetization of the material is proportional to the area of the hysteresis loop. Therefore, cores of transformers are made of materials with narrow hysteresis loops so that little energy will be wasted in the form of heat. Hysteresis loss in a transformer occurs due to magnetization saturation in the core of the transformer. Magnetic materials in the core will eventually become magnetically saturated when they are placed in a strong magnetic field, such as the magnetic field generated by an AC current. Hysteresis loss is associated with the phenomena of hysteresis and is an expression of the fact when ferromagnetic material is involved, not all the energy of the magnetic field is returned to the circuit when mmf is removed. It is known as hysteresis loss. When the magnetic circuits are subjected to time varying flux densities,mainly there are two causes of power loss in the form of heat in the iron core.The first losses is hysteresis loss and the second is the eddy current loss.Both of the losses are significant in determining the heating,rating,and efficiency of rotating electrical machines,transformers.

Hysteresis losses are assumed to generate heat to the first power of the frequency.

states that gutters should be nominally level (with a gradient of between mm/m and 3mm/m where practicable), can reduce the influence of the hysteresis loss.
