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.
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.
1.
Verify the local HMI setting AutoEnerg to be Off and ManEnerg to be DBLL.
2.
Set the parameter ManEnergDBDL to On.
3.
Apply a single-phase voltage of 30% GblBaseSelBus to the U-Bus and a single-phase voltage
of 30% GblBaseSelLine to the U-Line.
