Abstract

          Transformers are integral part of the power system. They are responsible for transmission of power to long distances with high efficiency. Hence, it is very important to protect the transformers from faults and to analyse the faults. Power engineers need to analyse the fault whether to ascertain its severity. It helps them to decide whether to continue with the operation of the transformer, do minor repair work or to replace the transformer completely and also in doing Periodic preventive maintenance. Many techniques are devised to understand the intensity of the fault.
