PROJECT TITLE :
Modeling, Analysis, and Detection of Internal Winding Faults in Power Transformers
The winding interturn fault is critical in power transformers since its result is not simply comprehensible at lower magnitude in the signatures of terminal voltages and currents. This paper presents a new and efficient approach for diagnosing the prevalence of incipient flip-to-flip short circuits in the windings of power transformers. The transformer is modeled in steady state and no-load operation. The analysis shows that the section distinction between the input voltage and input current in the faulty primary winding is changed in an exceedingly manner that creates it a sensible live to search out the fault. A set of laboratory experiments on a custom-engineered transformer below varied levels of faults confirms our theoretical analysis and results.
