Section 11
Testing functionality by secondary injection
1. Apply voltages V-Line (for example) = 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 trips within
the set
4. Increase the V-Bus to 110%
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
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 V-Line (for example) = 100%
GblBaseSelBus , with a phase difference equal to 0 degrees and a frequency difference lower
than
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 trips
for values lower than the set ones,
on the voltage connected to V-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 trip for
other values. See figure 52.

3. Change the phase angle between +dφ and -dφ and verify that the two outputs are activated
for phase differences between these values but not for phase differences outside, see
figure 52.
Testing the frequency difference
The frequency difference test should verify that operation is achieved when the
FreqDiffM frequency difference is lower than the set value for manual and auto synchronizing
FreqDiffA and FreqDiffM respectively and that operation is blocked when the frequency
check,
difference is greater.
Test with frequency difference = 0 mHz

VDiffSC . Check with both V-Line and V-Bus respectively lower than the other.
GblBaseSelBus , and the V-Line = 90% GblBaseSelLine and also the
PhaseDiffM and PhaseDiffA respectively are set to their final settings
FreqDiffA and FreqDiffM .
