Siemens SIPROTEC 7SJ80 User Manual

Voltage Difference
The parameters 6150 dV SYNCHK V2>V1 and 6151 dV SYNCHK V2<V1 can be set to adjust the permissible
voltage differences asymmetrically. The availability of two parameters enables an asymmetrical release to be
set.
Settings
Addresses which have an appended “A” can only be changed with DIGSI, under “Additional Settings”.
