8. Change the magnitude of the voltage and current for phase 1 to a value higher
than the set value
DU> and DI< .
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.
9.4.2.6 Completing the test
M1405-130 v5
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.
9.5 Control
SEMOD53560-1 v1
9.5.1 Synchrocheck, energizing check, and synchronizing
SESRSYN
M2377-3 v12
This section contains instructions on how to test the synchrocheck, energizing
check, and synchronizing function SESRSYN for single arrangements.
Prepare the IED for verification of settings outlined in Section "Preparing the IED
to verify settings" .
At commissioning and periodical checks, the functions shall be tested with the used
settings. To test a specific function, it might be necessary to change some setting
parameters, for example:
• AutoEnerg = Off / DLLB / DBLL / Both
• ManEnerg = Off
• Operation = Off / On
• Activation of the voltage selection function if applicable
The tests explained in the test procedures below describe the settings, which can be
used as references during testing before the final settings are specified. After
testing, restore the equipment to the normal or desired settings.
A secondary injection test set with the possibility to alter the phase angle and
amplitude of the voltage is needed. The test set must also be able to generate
different frequencies on different outputs.
The description below applies for a system with a nominal
frequency of 50 Hz but can be directly applicable to 60 Hz.
SESRSYN can be set to use different phases, phase to earth or
