Testing the energizing check

During the test of the energizing check function for a single bay arrangement, these voltage inputs
are used:
V-Line
V-Bus
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.
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 V-Line
and for a high voltage on the V-Bus. This corresponds to the energizing of a dead line to a live bus.
1. Apply a single-phase voltage 100%
VBase to the V-Line.
2. Check that the AUTOENOK and MANENOK outputs are activated.
3. Increase the V-Line to 60%
not be activated.
4. The test can be repeated with different values on the V-Bus and the V-Line.
Testing the dead bus live line (DBLL)
The test should verify that the energizing check function operates for a low voltage on the V-Bus
and for a high voltage on the V-Line. This corresponds to an energizing of a dead bus to a live line.
1. Verify the local HMI settings
2. Apply a single-phase voltage of 30%
VBase to the V-Line.
3. Check that the AUTOENOK and MANENOK outputs are activated.
4. Decrease the V-Line to 60%
should not be activated.
5. The test can be repeated with different values on the V-Bus and the V-Line.
Testing both directions (DLLB or DBLL)
1. Verify the local HMI settings
2. Apply a single-phase voltage of 30%
VBase to the V-Bus.
3. Check that the AUTOENOK and MANENOK outputs are activated.
4. Change the connection so that the V-Line is equal to100%
30%
5. The test can be repeated with different values on the V-Bus and the V-Line.
