Testing The Synchronizing Function - ABB Relion REG650 Commissioning Manual

1MRK 502 035-UEN A
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 = On / 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 individually 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 17
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 transferred 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.
