Transformer losses 1. Core loss or Iron loss a. Hysteresis loss in transformer : Hysteresis loss is due to reversal of magnetization in the transformer core. This loss depends upon the volume and grade of the iron, frequency of magnetic reversals and value of flux density. Steinmetz formula: W h = ηB max 1.6 fV (watts) where, η = Steinmetz hysteresis constant V = volume of the core in m 3 F = Frequency Energy loss in a transformer (Eddy current in the core ) b. Ed dy current loss in transformer : In transformer, AC current is supplied to the primary winding which sets up alternating magnetizing flux. When this flux links with secondary winding, it produces induced emf in it. But some part of this flux also gets...
