Fault analysis and diagnosis of a transformer are essential, as power quality is one of the primary concerns of the electric power utilities. Insulation failure within transformer windings is considered to be one of the most important causes of the failure of power transformers. A comparison of neutral currents at reduced and full voltages is carried out for detection of faults in a power transformer winding during impulse tests. If the fault is of a minor nature viz., inter-turn, the neutral… CONTINUE READING
