Abstract
Successful application of LVI methods to detect winding deformation after transformer short-circuit tests has made it feasible to use this technique as a maintenance tool to assess any deleterious effects of close-in faults on installed transformers. This report reviews Input and Voltage Differential methods, technique improvements and their application to field use. Short-circuit test comparisons are made with the Amplifier Differential method.
