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.
Procedure:
1. Apply a single-phase voltage 100% UBase to the U-Bus, and a single-phase
voltage 30% UBase to the U-Line.
2. Check that the AUTOENOK and MANENOK outputs are activated.
3. Increase the U-Line to 60% UBase and U-Bus to be equal to 100% UBase.
The outputs should not be activated.
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 from a live line.
Procedure:
1. Verify the local HMI settings AutoEnerg or ManEnerg to be DBLL.
2. Apply a single-phase voltage of 30% UBase to the U-Bus and a single-phase
voltage of 100% UBase to the U-Line.
3. Check that the AUTOENOK and MANENOK outputs are activated.
4. Decrease the U-Line to 60% UBase and keep the U-Bus equal to 30% UBase.
The outputs should not be activated.
5. The test can be repeated with different values on the U-Bus and the U-Line.
Testing both directions (DLLB or DBLL)
Procedure:
1. Verify the local HMI settings AutoEnerg or ManEnerg to be Both.
2. Apply a single-phase voltage of 30% UBase to the U-Line and a single-phase
voltage of 100% UBase to the U-Bus.
3. Check that the AUTOENOK and MANENOK outputs are activated.
4. Change the connection so that the U-Line is equal to100% UBase and the U-
Bus is equal to 30% UBase.
The outputs should still be activated.
5. The test can be repeated with different values on the U-Bus and the U-Line.
Testing the dead bus dead line (DBDL)
The test should verify that the energizing check function operates for a low voltage
on both the U-Bus and the U-Line, that is, closing of the breaker in a non-energized
system. Test is valid only when this function is used.
