Three-phase tripping

Connect the inputs from the protection functions to the input TRIN. 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 TRL1, TRL2, TRL3 will always be
activated at every trip and can be utilized on individual trip outputs if single-phase operating
devices are available on the circuit breaker even when a three-phase tripping scheme is
selected.
Set the function block to
example,
The typical connection is shown below in figure 4.

Single- and/or three-phase tripping

The single-/three-phase tripping operation mode will give single-phase tripping for single-
phase faults and three-phase tripping for multi-phase fault. This operating mode is always
used together with a single-phase autoreclosing scheme.
The single-phase tripping operation mode can include different options and the use of the
different inputs in the function block. Inputs TRINL1, TRINL2 and TRINL3 shall be used for trip
signals from functions with built-in phase selection logic such as distance or line differential
protection functions.
The inputs 1PTRZ and 1PTREF are used for single-phase tripping from functions which do not
have built-in phase selection logic:
• 1PTRZ can be connected to the carrier aided trip signal from the distance protection
scheme (it means that another distance protection function has seen or detected the
fault)
• 1PTREF can be connected to an earth fault function such as EF4PTOC or a carrier aided
trip signal from the earth fault protection scheme
