14.1.2 Functionality
M12275-3 v12
A function block for protection tripping and general start indication is always
provided as a basic function for each circuit breaker. It provides a settable pulse
prolongation time to ensure a trip pulse of sufficient length, as well as all
functionality necessary for correct co-operation with autoreclosing functions.
The trip function block includes a settable latch function for the trip signal and
circuit breaker lockout.
The trip function can collect start and directional signals from different application
functions. The aggregated start and directional signals are mapped to the IEC
61850 logical node data model.
