Making transformer losses part of the purchasing decision
The theory of transformer losses expressed as no-load loss and load loss is briefly reviewed. Mathematical expressions for per unit loss as a function of load are developed based both on rated and actual load. Present value equations are used to express the cost of losses as a function of transformer characteristics and discount rate. Three methods are presented for expressing the cost of loss in forms which can be used to evaluate bids.
