Setting of phase selection element
Phase selection is required only for faults on the protected line. Therefore, impedance reach
setting UVCZ is set to 120% of the positive-sequence impedance of the protected line. Impedance
angle setting UVC θ is set the same as the protected line angle.
Undervoltage setting UVCV is set higher than the estimated maximum fault voltage at the fault
point for a single-phase earth fault.
