Bydefinition, power factor is the cosine of the angle between the phase to neutralvoltages and the corresponding phase current. In this example, 18.2° is the anglebetween Van and Ia, Vbn and Ib, and Vcn and Ic. Since the relay is measuringphase-phase quantities, and Vab is the reference phasor, the angle displayed by therelay takes into consideration the 30° angle between phase-phase and phase-neutral voltages.
