Testing The Voltage Selection - ABB Relion 670 Series Commissioning Manual

1MRK 511 403-UEN E
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.
1. Verify the local HMI setting
2. Set the parameter
3. Apply a single-phase voltage of 30%
voltage of 30%
4. Check that the MANENOK output is activated after set
5. Increase the U-Bus to 80%
GblBaseSelLine . The outputs should not be activated.
6. Repeat the test with
Line voltage.

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 U-Line and a single-phase voltage of 100% GblBaseSelBus to the U-Bus.
If the UB1/2OK 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.
Testing the voltage selection for double breaker
This test should verify that correct voltage is selected for the measurement in the SESRSYN
function used for a diameter in a One-and-a-half breaker arrangement. Apply a single-phase
voltage of 100%
GblBaseSelBus to the U-Bus. Verify that correct output signals are generated.
1. Connect the analog signals to the voltage inputs, in pair of two for U1 and U2. (Inputs
U3PBB1, U3PBB2, U3PLN1, U3PLN2)
2. Activate the binary signals according to the used alternative. Verify the measuring
voltage on the synchronizing check function SESRSYN. Normally it can be good to verify
synchronizing check with the same voltages and phase angles on both voltages. The
voltages should be verified to be available when selected and not available when another
input is activated so connect only one voltage transformer reference at each time.
3. Record the voltage selection tests in a matrix table showing read values and AUTOSYOK/
MANSYOK signals to document the test performed.
