Testing The Voltage Selection - ABB Relion 670 Series Commissioning Manual

Section 11
Testing functionality by secondary injection
1. Verify the settings AutoEnerg or ManEnerg to be DBLL.
2. Apply a single-phase voltage of 30% GblBaseSelBus to the V-Bus and a single-phase voltage of
100% GblBaseSelLine to the V-Line.
3. Check that the AUTOENOK and MANENOK outputs are activated after set tAutoEnerg respectively
tManEnerg.
4. Decrease the V-Line to 60% GblBaseSelLine and keep the V-Bus equal to 30% GblBaseSelBus.
The outputs 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 AutoEnerg or ManEnerg to be Both.
2. Apply a single-phase voltage of 30% GblBaseSelLine to the V-Line and a single-phase voltage of
100% GblBaseSelBus to the V-Bus.
3. Check that the AUTOENOK and MANENOK outputs are activated after set tAutoEnerg respectively
tManEnerg.
4. Change the connection so that the V-Line is equal to100% GblBaseSelLine and the V-Bus is equal
to 30% GblBaseSelBus. The outputs should still be activated.
5. The test can be repeated with different values on the V-Bus and the V-Line.
Testing the dead bus dead line (DBDL)
The test should verify that the energizing check function trips for a low voltage on both the V-Bus and the
V-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 Disabled and ManEnerg to be DBLL.
2. Set the parameter ManEnergDBDL to Enabled.
3. Apply a single-phase voltage of 30% GblBaseSelBus to the V-Bus and a single-phase voltage of
30% GblBaseSelLine to the V-Line.
4. Check that the MANENOK output is activated after set tManEnerg.
5. Increase the V-Bus to 80% GblBaseSelBus and keep the V-Line equal to 30% GblBaseSelLine.
The outputs should not be activated.
6. Repeat the test with ManEnerg set to DLLB with different values on the V-Bus and the V-Line
voltage.
11.10.1.4

Testing the voltage selection

Testing the voltage selection for single CB arrangements
This test should verify that the correct voltage is selected for the measurement in the SESRSYN function
used in a double-bus arrangement. Apply a single-phase voltage of 100% GblBaseSelLine to the V-Line
and a single-phase voltage of 100% GblBaseSelBus to the V-Bus.
If the VB1/2OK inputs for the fuse failure are used, they must be activated, during tests below. Also verify
that deactivation prevents operation and gives an alarm.
1. Connect the signals above to binary inputs and binary outputs.
2. Connect the voltage inputs to the analog inputs used for each bus or line depending of the type of
busbar arrangement and verify that correct output signals are generated.
