1. Change the magnitude and angle of phase-to-phase voltage to achieve
impedances at test points P1, P2, …, P8.
2. For each test point, observe that the output signals STELEMST, STNDZL1
and STNDZL2 are activated.
Change setting parameter CharStartZ< to Quadrilateral and set OpLoadEnch to
On. Also, Set X1Start, REOverRLStart, XEOverXLStart, LineAng, AngLd,
RFPEStart and RFPPStart to default values. Set RLd such that it is lower than
RFPEStart/RFPPStart.
Phase-to-earth fault - quadrilateral characteristic

Test points that are to be considered for measurement accuracy of set reactive reach
are shown in Figure
15 and Table 17.
