Dead Bus Start (With Synchronous Generators Only)
If the busbar is de-energized, a dead bus start of the GCB or the MCB is performed. If closing commands for the
MCB and the GCB are issued simultaneously, priority is given to the MCB provided the discrete input "Enable
MCB" (terminal 54) has been enabled.
Parameter 145
GCB dead bus op.
ON
Dead bus start of the GCB ON/OFF
ON ................ A dead bus start is performed in the event of a de-energized busbar
and an open MCB. The subsequent screens of this function are dis-
played.
OFF .............. A dead bus start is not performed. The subsequent screens of this
function are not displayed.
Parameter 146
GCB dead bus op.
df max 0.00Hz
Maximum differential frequency for GCB dead bus start 0.05 to 5.00 Hz
The prerequisite to issuing a close command is that the monitored generator fre-
quency may deviate from the generator rated frequency by no more than this value.
Parameter 147
GCB dead bus op.
dV max. 00,0%
Maximum differential voltage for GCB dead bus start 01,0 to 15,0 %
L This value refers to the parameter "rated voltage in system" (Parameter 19).
The prerequisite to issuing a close command is that the monitored generator voltage
may deviate from the generator rated frequency by no more than this value.
Parameter 148
GCB dead bus op
max.time 000s
Maximum time for closing the GCB 0 to 999 s
If the GCB is to be closed onto a dead busbar, this timer is initiated at the start of
the breaker closing sequence. If the breaker fails to close before the configured
time expires, a class 1 alarm is issued.
Issuing of class F1 alarm
Parameter 149
MCB dead bus op.
ON
Dead bus closing of the MCB ON/OFF
ON ................ A dead bus closing of the MCB is performed in the event of a de-
energized busbar and an open GCB. The subsequent screens of this
function are displayed.
OFF .............. A dead bus closing of the MCB is not performed. The subsequent
screens of this function are not displayed.
