Figure 569: Thermal overcurrent protection function
Circuit breaker failure protection CCBRBRF1 is initiated via the START input by
number of different protection functions available in the IED. The 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.

Three arc protection ARCSARC1...3 stages are included as an optional function. The
arc protection offers individual function blocks for three arc sensors that can be
connected to the IED. Each arc protection function block has two different operation
modes, that is, with or without the phase and residual current check.
The operate signals from ARCSARC1...3 are connected to both trip logic TRPPTRC1
and TRPPTRC2. If the IED has been ordered with high speed binary outputs, the
individual operate signals from ARCSARC1...3 are connected to dedicated trip logic
TRPPTRC3...5. The outputs of TRPPTRC3...5 are available at high speed outputs
X110:HSO1, X110:HSO2 and X110:HSO3.
