Abstract

Abstract: The locations and severity of interturn short circuits in windings can be determined from the characteristic electromagnetic field parameters associated with such faults, which is crucial for their timely detection. This study establishes an electromagnetic coupling model for interturn short circuits in transformer windings and verifies its accuracy and effectiveness by comparing simulated and experimental winding currents under interturn short circuit conditions. Subsequently, the variations in winding currents, core flux, and winding flux when interturn faults occur in high-voltage windings are investigated. The effects of the number of short-circuited turns and the fault location on these parameters are further analyzed in depth. The findings of this study provide a theoretical basis for diagnosing interturn short circuits at different locations and of different severity in three-phase transformers.

Key words: transformer, interturn short circuit, electromagnetic coupling, winding current, magnetic field distribution
