Section 9
Testing functionality by secondary injection
82
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.
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)
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)
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.
