For example, using many separate rectangular (Preisach) units/domains (with certain distributions of them) to compose the transforming material [2] is one of the basic principles of models of hysteresis.
All cycles were started below the Mf temperature (fully martensitic state, where the transformed fraction (ξ) of the material is equal to 1).

Keywords: The “large five” system Transformer LCC model Cost Analysis
Abstract: Life Cycle Cost (LCC) Management is not only an advanced management concept but also an effective way to achieve the integration of high-efficacy and low-cost assets.
It belongs to material intensive products.
Two projects have been put forward: the first one, purchase a new transformer for replacement and updates the rating of the transformer capacity to, No-load loss, Load loss, Maximum load rate, and Largest load hours of use.The second project is to alter the original transformer, replacing the winding, insulating material and increasing some cooler.
