14.1.2 Application
M12252-3 v10
All trip signals from the different protection functions shall be routed through the
trip logic. In its simplest form, the trip logic will only link the TRIP signal to a
binary output and make sure that the trip duration is sufficient.
Tripping logic SMPPTRC can be used in single-phase and two-phase railway
supply systems.
One SMPPTRC function block should be used per each breaker.
To prevent closing of a circuit breaker after a trip, the function offers a lockout
function.
14.1.2.1 Tripping
M14828-7 v10
A simple application with tripping utilizes part of the function block. Connect the
inputs from the protection function blocks to the input TRIN to combine the
different function outputs to this input. Connect the output TRIP to the binary
outputs on the IO board.
This signal can also be used for other purposes internally in the IED. An example
could be the starting of breaker failure protection.
Set the required length of the trip pulse to for example, tTripMin = 150ms .
For special applications such as lockout refer to the separate section below. The
typical connection is shown below in figure
153 . Signals that are not used are
dimmed.
