Interturn short-circuit faults are the leading cause of power transformer's failure. If not detected at the incipient stage, these faults usually develop into more severe faults that would result in irreversible damage to the transformer, unexpected outages, and consequential losses. This paper presents a transformer interturn fault detection system (TIFDS) for the detection of an interturn fault...
A new impedance algorithm to protect power transformer is presented in this paper. The algorithm is based on three currents and three voltages measured at each side of the transformer. An edge detection technique using fast Fourier transform (FFT) provides inputs for an impedance scheme to properly detect and isolate faults within the transformer protection zone. The magnitudes of the current and...
