Impulse test is a routine test for transformers and is performed to assess their winding insulation strength. If any fault occur during impulse test, the winding current contain typical signature depending on the nature and type of the faults. Among the various impulse faults the series fault or shunt fault that may occur in the winding needs special(More)
The assessment of winding deformation during a short circuit test on a transformer has traditionally been treated as a hard computing problem. Recent developments using frequency response analysis have shown improved sensitivity for detection. The method can be further refined to work on line by concurrent excitation with a high frequency source. Soft(More)
