One of the major causes of failure of converter transformer is the incipient discharges caused due to deterioration of insulation. The insulation in the converter transformers is stressed not only by AC voltages but also with remnant DC voltages. The Acoustic Emission (AE) Technique can identify such incipient discharges in the converter transformer. In the present work, experimental studies were...
