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 UDiffSC is lower than 0.15 p.u.
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 UDiffSC.
