1.
Change the magnitude and angle of phase-to-earth voltage in phase L1 to achieve impedances
at test points P1, P2, ..., P16. At the same time, inject voltage magnitude of 0.0 V and current
of 0.0 A in phase L2.
2.
For each test point, observe that the output signals STELEMST and STNDZL1 are activated.
3.
Repeat the above test by injecting phase-to-earth voltage in phase L2 in accordance with test
points and steps described above and observe that the output signals STELEMST and
STNDZL2 are activated.
Quadrilateral characteristic
Change setting parameter CharStartZ< to Quadrilateral and set OpLoadEnch to On. Also, Set
X1Start, LineAng, ArgLd, and RFPEStart to default values. Ensure RLd value is lower than
RFPEStart.
