Abstract
Embodiments of the present disclosure disclose a method for calculating eddy current loss of a transformer, a storage medium and a device. The calculated eddy current loss of the transformer obtained by the method is relatively accurate, and the problem that in the relevant art, a coil temperature field cloud diagram under rated capacity of the transformer is influenced by electric conductivity of an iron core, so that the calculated eddy current loss is inaccurate is solved.
