摘要
Embodiments of the disclosure relate to detecting failure between turns in one or more windings of various objects. In one implementation, a fault detector uses a differential protection algorithm to detect a failure between turns in a three-phase bypass reactor winding. Various voltage and current measurements made on the three-phase bypass reactor are used to calculate a difference value between a voltage-based parameter and a current-based parameter. The voltage-based parameter is indicative of a normalized negative voltage unbalance and the current-based parameter is indicative of a normalized negative current imbalance. a coil winding failure is declared when the difference value is not zero.
