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)
M2377-276 v7
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)
M2377-289 v8
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.
1. Verify the settings AutoEnerg or ManEnerg to be DBLL .
2. Apply a single-phase voltage of 30% GblBaseSelBus to the U-Bus and a
single-phase voltage of 100% GblBaseSelLine to the U-Line.
3. Check that the AUTOENOK and MANENOK outputs are activated after set
tAutoEnerg respectively tManEnerg .
4. Decrease the U-Line to 60% GblBaseSelLine and keep the U-Bus equal to
30% GblBaseSelBus . 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)
M2377-306 v7
1. Verify the local HMI settings AutoEnerg or ManEnerg to be Both .
2. Apply a single-phase voltage of 30% GblBaseSelLine to the U-Line and a
single-phase voltage of 100% GblBaseSelBus to the U-Bus.
3. Check that the AUTOENOK and MANENOK outputs are activated after set
tAutoEnerg respectively tManEnerg .
4. Change the connection so that the U-Line is equal to100% GblBaseSelLine
and the U-Bus is equal to 30% GblBaseSelBus . 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)
M2377-323 v8
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.
