The phase discontinuity protection (PDNPSTOC1) provides protection for
interruptions in the normal three-phase load supply, for example, in downed
conductor situations. The operate signal of the phase discontinuity protection is
connected to the Master Trip and also to an alarm LED and the disturbance
recorder. The thermal overload protection (T1PTTR1) provides indication on
overload situations. The operate signal of the thermal overload protection is
connected to the Master Trip and also to an alarm LED. LED 4 is used for the
phase discontinuity protection operate indication, the same as for negative
sequence overcurrent protection operate indication, and LED 5 is used for the
thermal overload protection alarm indication.
The breaker failure protection (CCBRBRF1) is initiated via the start input by a
number of different protection stages 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 breaker failure
protection has two operating outputs: TRRET and TRBU. The TRRET operate
output is used for retripping its own breaker through the Master Trip 2. The TRBU
output is used to give a back-up trip to the breaker feeding upstream. For this
purpose, the TRBU operate output signal is connected to the output PO2 (X100:
8-9). LED 6 is used for back-up (TRBU) operate indication.

Figure 16: Arc protection
Arc protection (ARCSARC1...3) and autoreclosing (DARREC1) are included as
optional functions.

Application Manual
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, with or without the phase and residual current check. Operate
signals from the arc protection function blocks are connected to the Master Trip
and also to the alarm LED 10 as a common operate indication.
The autorecloser is configured to be initiated by operate signals from a number of
protection stages through the INIT1...5 inputs. It is possible to create individual
autoreclose sequences for each input.
The autoreclose function can be blocked with the INHIBIT_RECL input. By
default, the operation of selected protection functions are connected to this input. A
control command to the circuit breaker, either local or remote, also blocks the
autoreclose function via the CBXCBR-selected signal.
The circuit breaker availability for the autoreclosure sequence is expressed with the
CB_READY input in DARREC1. In the configuration, this signal is not connected
to any of the binary inputs. As a result, the function assumes that the breaker is
available all the time.
The autoreclose sequence in progress indication is connected to the alarm LED 11. | | |
