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:
•
•
•
•
•
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.
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):
