1. Apply voltages U-Line (for example) = 80% GblBaseSelLine and U-Bus =
80% GblBaseSelBusGblBaseSelBus with the same phase-angle and
frequency.
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
UDiffSC . Check with both U-Line and U-Bus
respectively lower than the other.
4. Increase the U-Bus to 110% GblBaseSelBus , and the U-Line = 90%
GblBaseSelLine and also the opposite condition.
5. Check that the two outputs for manual and auto synchronism are not
activated.
Testing the phase angle difference
M2377-215 v8
The phase angle differences PhaseDiffM and PhaseDiffA respectively are set to
their final 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.
1. Apply voltages U-Line (for example) = 100% GblBaseSelLine and U-Bus =
100% GblBaseSelBus , with a phase difference equal to 0 degrees and a
frequency difference lower than FreqDiffA and FreqDiffM .
2. Check that the AUTOSYOK and MANSYOK outputs are activated.
The test can be repeated with other phase difference values to verify that the
function operates for values lower than the set ones,
PhaseDiffM and
PhaseDiffA . By changing the phase angle on the voltage connected to U-Bus,
between ± dφ degrees, the user can check that the two outputs are activated
for a phase difference lower than the set value. It should not operate for other
values. See figure
13 .

3. Change the phase angle bdφ and -dφ and verify that the two outputs
are activated for phase differences between these values but not for phase
differences outside, see figure
