tripping and autoreclosing is used on the line, both breakers are normally set up for
1/3-pole tripping and 1/3-phase autoreclosing. Alternatively, the breaker chosen as
master can have single-pole tripping, while the slave breaker could have three-pole
tripping and autoreclosing. In the case of a permanent fault, only one of the breakers
has to be operated when the fault is energized a second time. In the event of a transient
fault the slave breaker performs a three-pole reclosing onto the non-faulted line.
The same philosophy can be used for two-pole tripping and autoreclosing.
To prevent closing of a circuit breaker after a trip, the function offers a lockout
function.

Three-pole tripping

Connect the inputs from the protection functions to the input TRINP_3P. The
TMGAPC function block is used to combine up to 32 inputs into one output. 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. The three outputs TR_A, TR_B, TR_C
will always be activated at every trip and can be utilized on individual trip outputs if
single-pole operating devices are available on the circuit breaker even when a three-
pole tripping scheme is selected.
Set the function block to Program = 3 phase and set the required length of the trip
pulse to for example, tTripMin = 150ms.
The typical connection is shown below in figure 199.
