Testing the voltage difference
Set the voltage difference to 0.15 p.u. on the local HMI, and the test should check that
operation is achieved when the voltage difference
The settings used in the test shall be final settings. The test shall be adapted to site setting
values instead of values in the example below.
Test with no voltage difference between the inputs.
Test with a voltage difference higher than the set
1. Apply voltages U-Line (for example) = 80%
GblBaseSelBus
2. Check that the AUTOSYOK and MANSYOK outputs are activated.
3. The test can be repeated with different voltage values to verify that the function
operates within the set
than the other.
4. Increase the U-Bus to 110%
also the opposite condition.
5. Check that the two outputs for manual and auto synchronism are not activated.
Testing the phase angle difference
The phase angle differences
settings and the test should verify that operation is achieved when the phase angle difference
is lower than this value both leading and lagging.
Test with no voltage difference.
