2 Functions
Intertrip/Remote
If the intertrip function is activated, it will automatically start when the differential
tripping
protection trips.
If the relevant binary inputs are allocated and activated by an external source, the in-
tertrip signal is transmitted as well. In this case, the signal to be transmitted can be
delayed with address 1303 T-ITRIP BI. This delay stabilizes the originating signal
against dynamic interferences which may possibly occur on the control cabling.
Address 1304 T-ITRIP PROL BI is used to extend a signal after it has been effec-
tively injected from an external source.
The reaction of a device when receiving an intertrip/remote tripping signal is set at
address 1302 I-TRIP RECEIVE. If it is supposed to cause tripping, set the value
Trip. If the received signal, however, is supposed to cause an alarm only, Alarm
only must be set if this indication is to be further processed externally.
The setting times depend on the individual case of application. A delay is necessary if
the external control signal originates from a disturbed source and a restraint seems
appropriate. Of course, the control signal has to be longer than the delay for the signal
to be effective. If the signal is processed externally at the receiving end, a prolongation
time might become necessary for the transmitting end so that the reaction desired at
the receiving end can be executed reliably.
