1. Simulate normal operating conditions with the three-phase currents in phase with their
corresponding phase voltages and with all of them equal to their rated values.
2. Change the voltages and currents in all three phases simultaneously.
The voltage change must be greater than the set value for
must be less than the set value for
•
•
3. Apply normal conditions as in step 1.
The BLKU, BLKZ and 3PH signals should reset, if activated, see step
4. Change the voltages and currents in all three phases simultaneously.
The voltage change must be greater than the set value for
must be more than the set value for
The BLKU, BLKZ and 3PH signals should not appear.
5. Repeat step 2.
6. Connect the nominal voltages in all three phases and feed a current below the operate
level in all three phases.
7. Keep the current constant. Disconnect the voltage in all three phases simultaneously.
The BLKU, BLKZ and 3PH signals should not appear.
8. Change the magnitude of the voltage and current for phase 1 to a value greater than the
set value for
9. Check that the start output signals STDUL1 and STDIL1 and the general start signals
STDU or STDI are activated.
10. Check that the start output signals for the current and voltage phases 2 and 3 are
activated by changing the magnitude of the voltage and current for phases 2 and 3.

Completing the test

Continue to test another function or end the testing by setting the parameter
under Main menu/Tests/IED test mode/TESTMODE:1. If another function is tested, then set
the parameter
system supervision/SDDRFUF/SDDRFUF:1 for the function, or for each individual function in a
chain, to be tested next. Remember to set the parameter
function that has been tested.

Synchrocheck, energizing check, and synchronizing SESRSYN

This section contains instructions on how to test the synchrocheck, energizing check, and
synchronizing function SESRSYN for single, double and 1½ breaker arrangements.
This section contains instructions on how to test the synchrocheck and energizing check for
single CB with or without the synchronizing function.
Prepare the IED for verification of settings as outlined in section
settings.

The BLKU and BLKZ signals appear without any time delay. The BLKZ signal will be
activated only if the internal deadline detection is not activated at the same time.
3PH should appear after 5 seconds, if the remaining voltage levels are lower than
UDLD< of the DLD function.
