Section 10
Testing functionality by secondary injection
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%
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%
voltage 30%
2. Check that the AUTOENOK and MANENOK outputs are activated after set
respectively
3. Increase the U-Line to 60%
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
2. Apply a single-phase voltage of 30%
voltage of 100%
3. Check that the AUTOENOK and MANENOK outputs are activated after set
respectively
4. Decrease the U-Line to 60%
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
2. Apply a single-phase voltage of 30%
voltage of 100%
3. Check that the AUTOENOK and MANENOK outputs are activated after set
respectively
4. Change the connection so that the U-Line is equal to100%
is equal to 30%
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.
