Figure 23: Autorecloser function
Circuit breaker failure protection CCBRBRF1 is initiated via the START input by a
number of different protection functions available in the protection relay as well as
externally by binary input X110:BI1. The circuit breaker failure protection function
offers different operating modes associated with the circuit breaker position and the
measured phase and residual currents.
The circuit breaker failure protection function has two operating outputs: TRRET and
TRBU. The TRRET operate output is used for retripping its own breaker through
TRPPTRC2_TRIP. The TRBU output is used to give a backup trip to the breaker
feeding upstream. For this purpose, the TRBU operate output signal is connected to the
binary output X100:PO2.

The operate signals from the protection functions are connected to the two trip logics:
TRPPTRC1 and TRPPTRC2. The output of these trip logic functions is available at
binary output X100:PO3 and X100:PO4. The trip logic functions are provided with a
