and the bus voltage is above 80% of the bus base voltage UBase, according to the
setting GblBaseSelBus.
• DBLL, Dead Bus Live Line, the bus voltage is below 40% of the bus base voltage
UBase, according to the setting GblBaseSelBus about the Global Base Value group,
and the line voltage is above 80% of the line base voltage UBase, according to the
setting GblBaseSelLine.
• Both, energizing can be done in both directions, DLLB or DBLL.
ManEnergDBDL
If the parameter is set to Enabled, manual closing is enabled when line voltage is below
40% of the line base voltage UBase, according to the setting GblBaseSelLine about the
Global Base Value group, and when bus voltage is below 40% of the bus base voltage
UBase, according to the setting GblBaseSelBus and also ManEnerg is set to DLLB, DBLL
or Both.
tAutoEnerg and tManEnerg
The purpose of the timer delay settings, tAutoEnerg and tManEnerg, is to ensure that the
dead side remains de-energized and that the condition is not due to a temporary
interference. Should the conditions not persist for the specified time, the delay timer is
reset and the procedure is restarted when the conditions are fulfilled again. Circuit breaker
closing is thus not permitted until the energizing condition has remained constant
throughout the set delay setting time.

11.2.2 Application
Automatic reclosing is a well-established method for the restoration of service in a power
system after a transient line fault. The majority of line faults are flashover arcs, which are
