5.2.6 Operation principle
The basic impedance algorithm for the operation of the phase selection measuring elements is the
same as for the distance zone measuring function. Phase selection with load encroachment,
quadrilateral characteristic FDPSPDIS (21) includes six impedance measuring loops; three intended
for phase-to-ground faults, and three intended for phase-to-phase faults as well as for three-
phase faults.
The difference, compared to the distance zone measuring function, is in the combination of the
measuring quantities (currents and voltages) for different types of faults.
