Application of Modern Technology for Fault Diagnosis in Power Transformers Energy Management

A transformer is the most important equipment for power supply to consumers. For uninterrupted power supply to consumers proper maintenance particularly preventive maintenance is very much necessary. The failure in magnetic, electric and dielectric circuits as well as structural failure may cause extensive damage to the equipment and surroundings. Proper operation and maintenance procedure may help to prevent failure and extend life of operation of the transformer. Continuous monitoring to health of the transformer and analyzing the history of past failures may indicate the type of maintenance required & facilitate identifying incipient faults. An overview of recently developed mythologies has been covered in the present paper along with planned strategy for curbing catastrophic failures creeping In service-transformers. The methods suggested in the paper are helpful in reducing failure and extending life of both the power transformers & distribution transformers.
