Abstract	The paper describes a procedure for the representation of hysteresis in the laminations of power transformers in the simulation of electromagnetic transient phenomena. The model is based on the recognition that in today's iron cores the hysteresis loops are narrow and therefore the modeling details are only important in relation to the incurred losses and the associated attenuation effects. The resultant model produces losses proportional to the square of the flux density, as expected from measurement data. It is formulated as a simple, linear relationship between the variation B-B/sub re/spl nu, of the magnetic flux density B after a reversal point B/sub re/spl nu and the resulting additional field intensity H/sub hyst/. This idea can be easily implemented in existing transformer models with or without frequency dependent modeling of eddy currents in the laminations. It has been found that in simulation tests the representation of hysteresis is not necessary those situations have been described where the modeling of hysteresis appears to be more meaningful.<>
