Trigger Modes
There are three trigger modes for the
BF module available. In addition to that, there are three assignable trigger inputs
available that might trigger the
BF module even if they are not assigned within the breaker manager onto the breaker
that is to be monitored.
•
All Trips: All trip signals that are assigned to this breaker (within the trip manager) will start the BF module (please refer
also to section “Trigger signals of the Breaker Failure“).
•
Current Trips: All current trips that are assigned to this breaker (within the trip manager) will start the BF module
(please refer also to section “Trigger signals of the Breaker Failure“).
•
External Trips: All external trips that are assigned to this breaker (within the trip manager) will start the BF module
(please refer also to section ”Trigger signals of the Breaker Failure”).
•In addition, the User can also select
none
(e.g.: if the User intends to use one of the three additional assignable trigger
inputs).
Those trips can exclusively start the breaker failures that are assigned
within the trip manager to the breaker that is to be supervised. In contrast
to that the additional three triggers 1-3 will trigger the
BF
module even if
they are not assigned onto the breaker within the corresponding breaker
manager.
Select the winding side (Breaker, Winding) from which the measured
currents should be taken in case this protective device provides more than
one current measurement card.
This Notice applies to protective devices that offer control functionality
only! This protective element requires, that a switchgear (Breaker) is
assigned to it. It is allowed only to assign switchgears (Breaker) to this
protective element, whose measuring transformers provide measuring data
to the protective device.
Breaker Failure Lockout
The signal of the Breaker Failure is latched. This signal can be used to block the breaker against a switching on
attempt.
