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

11.10.1 Synchrocheck, energizing check, and synchronizing SESRSYN (25)
This section contains instructions on how to test the synchrochecksynchronism check, energizing
check, and synchronizing function SESRSYN (25) for single, double and breaker-and-a-half
arrangements.
Prepare the IED for verification of settings as outlined in section
section "Preparing for test"
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 = Disabled / DLLB / DBLL / Both
•
ManEnerg = Disabled
•
Operation = Disabled / Enabled
•
• 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 60 Hz but
can be directly applicable to 50 Hz. SESRSYN (25) can be set to use different
phases, phase to ground or phase to phase. Use the set voltages instead of what is
indicated below.
