摘要：

Improved models for current transformers, potential transformers and capacitive voltage transformers for a relay software library are presented in the paper. The magnetising characteristic in each of these transformers is based on the non-linear power curve formulation of Lucas [4]. The flux-current loops of the transformer core are self generated rather than predetermined or based on look up tables. The results presented show that the models developed for the transformers behave as expected, and agree with reported field investigations.
