• 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 = 10.74 kV
• CURRENT = 20918 A
• R = 7.37%
• X = 53.40%
• ROTORANG = -3.09 rad
Note that these values identify a point inside the lens characteristic, in the zone
2, that is close to the point RE. The START is issued, but no TRIP is
performed.
Execution of the dynamic test

The test may be performed by using two states of a sequence tool that is a basic
feature of test sets.
• State 1: pre-test condition.
Steady voltage and current are applied in order to get a steady high impedance,
that is, a point in the plane R-X which is far away from the lens characteristic.
Define the following three-phase symmetrical quantities (the phase angle is
related to phase L1):
