Figure A-51 Voltage connections to three wye-connected voltage transformers and additionally
to any phase-to-phase voltage (for synchronism check for example)
The terminal markings in brackets apply to the devices 7SJ623/7SJ624, the remaining to devices 7SJ64
Figure A-52 Voltage transformer connections of two phase-to-phase voltages in V-connection.
In this connection, determination of zero-sequence voltage V0 is not possible.
Functions using zero-sequence voltage must be disabled.
The terminal markings in brackets apply to the devices 7SJ623/7SJ624, the remaining to devices 7SJ64
