1.
Set the following parameters:
•
•
•
•
•
2.
Set a constant voltage input of UL1 = 63.5 V at 0° and UL2 = 63.5 V at 180° secondary and a
current signal at IL1 = 1A at 0° and IL2 = 1A at 180°.
3.
Ensure that the P output of CMMXU function has exceeded 10 MW and remains stable.
4.
Change the current signal at IL1= 2A at 0° and IL2= 2A at 180°. Both START and STARTRISE
signals should be active for 100 ms.
5.
Change the current signal at IL1= 1A at 0° and IL2= 1A at 180°. Both START and STARTLOW
signals should be active for 100 ms.

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.

Synchrocheck, energizing check, and synchronizing SESRSYN
This section contains instructions on how to test the synchrocheck, energizing check, and
synchronizing function SESRSYN.
Prepare the IED for verification of settings as outlined in section
section
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
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.
