SYNCHK CLOSE PERM:
General Closing permission of the Synchronism unit. It contemplates all possible
situations, live line-live bus conditions, and the closing permission logics (dead line-
dead bus, live line- dead bus, dead line-live bus).
Note
: in case the Function is
disabled, the Closing permission signal will be activated in order not to interfere with
possible logics where it is included. If the synchronism unit is enabled, this signal will
only be activated in the closing conditions established by setting.
Synchrocheck COND OP:

DL-DB OPERATION: Closing permission in dead line – dead bus condition.
DL-LB OPERATION: Closing permission in dead line – live bus condition.
LL-DB OPERATION: Closing permission in live line – dead bus condition.
SLIP CONDITION:
Internal signal indicating frequency slip between the line voltage and bus voltage
phasors.
BUS FREQ > LINE FREQ:
Busbar Frequency higher than line frequency
BUS FREQ < LINE FREQ:
Busbar Frequency lower than line frequency
VOLTAGE DIFFERENCE
:
Voltage difference between the line and the busbar in volts (secondary values), only
available if the Synchrocheck element is enabled.
FREQ. DIFFERENCE
:
Frequency difference between the line and the busbar in Hz, only available if the
