Technical manual
BU input signals for bay protection
Description
Blocks the protection output signals of the respective bay unit. Internal
processing of the functions continues and therefore measurements and
signals continue to be displayed on the local HMI.
The protection functions and settings assigned to parameter set 1, 2, 3, or
4, respectively, are active. They remain active after the signal has been
reset.
In addition to the bay protection input signals in this table, which are
always available, use can also be made of the signals configured for the
binary signal input block of the bay protection. The number of these
signals depends on the protection functions and signals included in the
bay protection.
BU general output signals
Description
Tripping command generated by the external input 11105_EXTERNAL
TRIP.
Tripping command generated by the station protection intertripping
function (BBP, BFP t2 etc).
Any of the protection functions that are capable of tripping an entire
section of busbar (intertripping) can initiate a remote trip signal.
Protection functions of this kind are: BBP, BFP, EFP, or the command
EXTERNAL TRIP.
Remote tripping can only take place if a fault cannot be cleared by the
circuit-breaker in the bay concerned. This applies in the following cases:
•
•
•
•
More details on special application cases are given in the
Manual .
Generates a multi-pole trip for test purposes. Either controlled by the
binary input signal 11115_Ext_Test_TRIP, or by the LHMI Test Trip menu.
If both, the 11115_Ext_Test_TRIP and LHMI Test Trip function are
configured and used simultaneously, 21120_EXT_TEST_TRIP results in an
OR function of both possible inputs.
Please refer to
Test Trip function.
