Four stages are offered for non-directional earth-fault protection. One stage is
dedicated to sensitive earth-fault protection. Based on the order code, the
configuration can also include an optional harmonic-based earth-fault
(HAEFPTOC) protection.
All operate signals are connected to the Master Trip as well as to the alarm LEDs.
LED 2 is used for directional earth-fault and LED 3 for the sensitive earth-fault
protection operate indication.

Figure 40: Phase discontinuity, thermal overload and circuit breaker failure
protection
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

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.

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. The INIT6 input in the autorecloser
function block is controlled by a binary input 2 (X110:3-4) enabling the use of the
external start command. 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
