Synchrocheck, energizing check, and synchronizing SESRSYN

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 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
• 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.
Figure 21
description describes the test of the version intended for one bay.

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 phase to phase. Use the set voltages instead of what is indicated
below.
