Check that the service values (VOLTAGE, CURRENT, R(%), X(%)) are
according to the injected quantities and that ROTORANG is close to 3.14 rad.
For this particular injection the service values are:
•
VOLTAGE = 5.31 kV
•
CURRENT = 20918 A
•
R = -0.26%
•
X = -26.65%
•
ROTORANG = -3.06 rad
Note that these values identify a point inside the lens characteristic in zone 1
that is close to the point SE. The START is issued, but no TRIP is performed.
