7. Activate the BLOCK binary input.
8. Activate EXTPDIND binary input.
NO TRIP signal should appear.
9. Reset both BLOCK and EXTPDIND binary inputs.
10. If Internal detection logic Contact function selection = ContSel setting equals
Pole position from auxiliary contacts. Then set inputs
POLE1OPN...POLE3CL in a status that activates the pole discordance logic
and repeats step 2 to step 6.
11. Unsymmetrical current detection with CB monitoring: Set measured current
in one phase to 110% of current release level. Activate CLOSECMD and
measure the operating time of the CCPDSC protection.
Use the TRIP signal from the configured binary output to stop the timer.
12. Deactivate the CLOSECMD: Set measured current in one phase to 90% of
Current Release level. Activate CLOSECMD.
NO TRIP signal should appear.
13. Repeat the previous two steps using OPENCMD instead of CLOSECMD.
Asymmetry current detection with CB monitoring: Set all three currents to
110% of Current Release level. Activate CLOSECMD.
NO TRIP signal should appear due to symmetrical condition.
14. Deactivate the CLOSECMD. Decrease one current with 120% of the current
unsymmetrical level compared to the other two phases. Activate
CLOSECMD and measure the operating time of the CCPDSC protection.
Use the TRIP signal from the configured binary output to stop the timer.
15. Deactivate the CLOSECMD. Decrease one current with 80% of the current
unsymmetrical level compared to the other two phases. Activate
CLOSECMD.
NO TRIP signal should appear.

Completing the test

Continue to test another function or end the test by changing the TESTMODE
setting to Off. Restore connections and settings to their original values, if they were
changed for testing purposes.

Directional underpower protection GUPPDUP

Prepare the IED for verification of settings outlined in Section
to verify settings".

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
