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.
This section contains instructions on how to test the synchrochecksynchronism check and
energizing check for single CB with or without the synchronizing function.
Prepare the IED for verification of settings as outlined in 5.1 "Preparing the IED to verify
settings" .
Values of the logical signals for SESRSYN (25) are available on the local HMI under
Main menu/Tests/Function status/Control/SESRSYN(25,SYNC)/SESRSYN:X . The
Signal Monitoring in PCM600 shows the same signals that are available on the local HMI.
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 50
Hz but can be directly applicable to 60 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.
Figure 13 shows the general test connection principle, which can be used during testing.
This description describes the test of the version intended for one bay.
Figure 14 shows the general test connection for a breaker-and-a-half diameter with one-
phase voltage connected to the line side.
