Section 11
Testing functionality by secondary injection
Testing the dead bus live line (DBLL)
The test should verify that the energizing check function trips 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 settings
2. Apply a single-phase voltage of 30%
of 100%
3. Check that the AUTOENOK and MANENOK outputs are activated after set
respectively
4. Decrease the V-Line to 60%
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
2. Apply a single-phase voltage of 30%
of 100%
3. Check that the AUTOENOK and MANENOK outputs are activated after set
respectively
4. Change the connection so that the V-Line is equal to100%
equal to 30%
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
2. Set the parameter
3. Apply a single-phase voltage of 30%
of 30%
4. Check that the MANENOK output is activated after set
5. Increase the V-Bus to 80%
The outputs should not be activated.
6. Repeat the test with
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%
to the V-Line and a single-phase voltage of 100%
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.
