Example of measurement via transformer
In the 3 function groups values are taken from the following table and entered for the adaptation factor 6121
Balancing U1/U2. Via binary input

>Sy8 wirks
the synchronizing function suitable for
the current transformer tap can be selected. This can occur directly via binary input or be derived from the
CFC.

The parameter 6122 ANGLE ADJUSTM. is used to correct any phase angle errors between the voltage trans-
formers in degree steps. A possible correction value should be derived during commissioning.
Using the setting parameters Balancing U1/U2 and ANGLE ADJUSTM. system versions can be managed
where voltage transformers are connected differently or different voltage transformers are used on side 1 and
side 2. The setting can be explained by two examples. In Figure 2-30 the two-pole isolated voltage trans-
formers are connected to different phase-to-phase voltages. Both primary and secondary voltages are equal.
