heal.abstract	This paper presents an investigation on the separation of no-load losses into hysteresis and eddy current losses. The two-temperatures and the two-frequency methods are used to separate the losses in a transformer core. Two measurements are required for the calculation of the eddy and hysteresis losses. The methodologies are applied to a commercial 15 kVA shell-type, single-phase distribution transformer, with core lamination thickness of 0.23 mm. The main contribution of this paper is the presentation of a practical and validated example for the accurate computation of eddy current losses and hysteresis losses in distribution transformers.	en
