Figure C-15
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 7SJ623/4/5/6, the remaining to devices 7SJ64

Figure C-16 Voltage transformer connections of two phase-to-phase voltages in open delta voltageconnec-
tion. In this connection, determination of zero-sequence voltage V0 is not possible. Functions
using zero-sequence voltage must be disabled.
