Abstract
Excitation current tests on power transformers in the field have been developed for the detection and location of certain types of faults. Special techniques are explained for application to three-phase transformers to determine the specific phase in which a fault exists. Examples are cited to show how excitation current tests have assisted in the diagnosis of fault conditions.
