Sync Function Group 1; Setting Notes - Siemens SIPROTEC 4 7VE61 Manual

SYNC Function group 1

2.2.2
Depending on the device variants, parametrization possibilities are provided for up to eight different synchro-
nizing functions. The following describes the setting notes, parameter and annunciations for the first synchro-
nising function (SYNC Function group 1). The same applies to function groups 2 to 8.

General
On setting the P.System Data 1 (see Section
significance for the synchronizing function:

8 was set as present. The operating mode can be preselected:
1ph Sync check corresponds to the classical synchronizing function with in each case single-phase connec-
tion of the voltages to be compared. Observe thereby that this selection involves a fixed allocation between
synchronizing function group and voltage channels. The allocation is shown in the following table
