Tripping logic common 3-phase output SMPPTRC (94)

Identification
Function description
Tripping logic common 3-phase output
Application
All trip signals from the different protection functions shall be routed through the trip
logic. In its simplest alternative the logic will only link the internal TRIP signals to a
binary output and make sure that the pulse length is long enough.
The tripping logic common 3-phase output (SMPPTRC ,94) offers only three-pole
tripping. A three-pole trip for all faults offers a simple solution and is often sufficient in
well meshed transmission systems and in High Voltage (HV) systems.
One SMPPTRC (94) function block should be used for each breaker, if the object is
connected to the system via more than one breaker.
To prevent closing of a circuit breaker after a trip the function can block the closing of the
circuit breaker (trip lock-out).
Three-pole tripping
A simple application with three-pole tripping from the tripping logic common 3-phase
output SMPPTRC utilizes part of the function block. Connect the inputs from the
protection function blocks to the input TRINP_3P. If necessary (normally the case) use
the trip matrix logic TMAGGIO to combine the different function outputs to this input.
Connect the output TRIP to the required binary outputs.
