Energy technique procedure for computing the leakage reactance in transformers is presented. This method is very efficient compared with the use of flux element and image technique and is also remarkably accurate. Examples of calculated leakage inductances and the short circuit impedance are given for illustration. For validation, the results are compared with the results obtained using practical tests for 3 types of a small single-phase transformer, 3-phase distribution transformers and a high voltage test transformer were studied.
