Abstract :
A digital algorithm for detecting faults in single-phase and three-phase power transformers is proposed. The algorithm is suitable regardless of whether it is possible to measure winding currents. The algorithm does not require B-H curve data. A variety of operating conditions simulated on a computer were used to test the algorithm. The results show that it performs well
