This paper describes a new phase selector that operates reliably during many unfavorable conditions, such as high fault resistance, high load flow, power swing, Current Transformer (CT) saturation, converter-based generation, weak infeed. The phase selector is based on the angular relationship between the sequence current components and sequence voltage components. The use of voltages and currents is dynamically selected. Some complimentary methods are added for phase selection during power swings. Matlab Simulink® simulations are performed to check the operation of the mentioned phase selector and to demonstrate its reliability. Oscillographic records from real faults are also analyzed.
