7. Check that STALARM signal is set after 1.0s and backup trip is blocked.
8. Reset START signal after 3.5s, ensure that STALARM reset immediately.
9. Set START after 3.6s, ensure that backup trip is set after t2 backup trip delay has expired (3.750 s).
10.4.7.11 Test of FollowStart&Mode behaviour
1. Set StartMode = FollowStart&Mode.
2. Set FunctionMode = Current.
3. Set RetripMode = UseFunctionMode.
4. Use default value for tStartTimeout = 1.0 s.
5. Use default value for time delay backup trip t2 = 0.150 s.
6. Use default value for time delay re-trip t1 = 0.000 s.
7. Leave the inputs for CB close inactivated. These signals should not influence.
8. Apply START signal, and after 0.200 s apply the current above the set IPPU value.
9. Check that STALARM does not come and that re-trip TRRET is instantly set at 0.200s while the
backup trip TRBU set only when t2 expires at 0.200 + 0.150s.
10.4.7.12 Test of FollowStart behaviour
1. Set StartMode = FollowStart.
2. Set FunctionMode = Current.
3. Set RetripMode = UseFunctionMode.
4. Use default value for tStartTimeout = 1.0 s.
5. Use for example the default value for time delay backup trip t2 = 0.150 s.
6. Use for example the default value for time delay retrip t1 = 0.000 s.
7. Leave the inputs for CB close inactivated. These signals should not influence.
8. Apply START signal, and after 0.200 s apply the current above the set IPPU value.
9. Check that STALARM does not come and that both re-trip TRRET and backup trip TRBU comes
instantly at 0.200 s (that is, as soon as current is given to the function).
10.4.8 Completing the test
Continue to test another function or end the test by changing the TESTMODE setting to Disabled.
Restore connections and settings to the original values, if changed for testing purposes.
10.4.9 Directional underpower protection GUPPDUP (37)
Prepare the IED for verification of settings as outlined in section
for test" in this chapter.
10.4.9.1 Verifying the settings
The underpower protection shall be set to values according to the real set values to be used.
The test is made by means of injection of voltage and current where the amplitude of both current and
voltage and the phase angle between the voltage and current can be controlled. During the test, the
analog outputs of active and reactive power shall be monitored.
