Testing The Synchronizing Function - ABB Relion 650 Series Commissioning Manual

Section 5
Testing functionality

• 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 alter the phase angle by
regulation of the resistive and reactive components 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 transferred to 60 Hz. The
synchronizing function can be set to use different phases, phase to
earth or phase to phase. Use the set voltages instead of what is
indicated below.
Figure 12 shows the general test connection principle, which can be used during
testing. This description describes the test of the version intended for one bay.
