Protective Elements
Synchrocheck Override Conditions
If enabled the following conditions can override the synchrocheck function:
•
LBDL = Live Bus – Dead Line
•
DBLL = Dead Bus – Live Line
•
DBDL = Dead Bus – Dead Line
Also the synchrocheck function can be bypassed by an external source.
When the synchrocheck function is overridden or bypassed,
synchronization has to be secured by other synchronizing systems before
breaker closing!
