Testing The Energizing Check - ABB RER670 Commissioning Manual

Section 10
Testing functionality by secondary injection
10.9.1.3
134
The voltage difference between the voltage connected to U-Bus and U-Line
should be 0%, so that the AUTOSYOK and MANSYOK outputs are activated
first.
2. Change the U-Line voltage connection to U-Line2 without changing the
setting on the local HMI. Check that the two outputs are not activated.

Testing the energizing check

During the test of the energizing check function for a single bay arrangement, these
voltage inputs are used:
U-Line UL1 or UL2 line voltage inputs on the IED
U-Bus Bus voltage input on the IED
General
When testing the energizing check function for the applicable bus, arrangement
shall be done for the energizing check functions. The voltage is selected by
activation of different inputs in the voltage selection logic.
Live voltage level is fixed to 80% UBase and dead voltage level to fixed 40%
UBase.
The test shall be performed according to the settings for the station. Test the
alternatives below that are applicable.
Testing the dead line live bus (DLLB)
The test should verify that the energizing check function operates for a low voltage
on the U-Line and for a high voltage on the U-Bus. This corresponds to the
energizing of a dead line to a live bus.
1. Apply a single-phase voltage 100% GblBaseSelBus to the U-Bus, and a
single-phase voltage 30% GblBaseSelLine to the U-Line.
2. Check that the AUTOENOK and MANENOK outputs are activated after set
tAutoEnerg respectively tManEnerg.
3. Increase the U-Line to 60% GblBaseSelLine and U-Bus to be equal to 100%
GblBaseSelBus. The outputs should not be activated.
4. The test can be repeated with different values on the U-Bus and the U-Line.
Testing the dead bus live line (DBLL)
The test should verify that the energizing check function operates for a low voltage
on the U-Bus and for a high voltage on the U-Line. This corresponds to an
energizing of a dead bus to a live line.
