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
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.
shows the general test connection principle, which can be used during
testing.
