nctional diagrams describe the IED’s protection functionality in detail and
picture the factory set default connections.
Four overcurrent stages are available for overcurrent and short-circuit protection.
Three of them include directional functionality (DPHxPDOC). The non-directional
instantaneous stage (PHIPTOC1) can be blocked by energizing the binary input 1
(X120:1-2). Two negative-sequence overcurrent stages (NSPTOC1 and
NSPTOC2) are available for phase unbalance protection. The inrush detection
block’s (INRPHAR1) output BLK2H enables either blocking the function or
multiplying the active settings for any of the shown protection function blocks.

Figure 56: Directional overcurrent protection
All operate signals are connected to the Master Trip and to the alarm LEDs. LED 1
is used for overcurrent and LED 4 for negative-sequence overcurrent protection
operate indication. LED 4 is also used for phase discontinuity protection operate
indication.

The upstream blocking from the start of the directional overcurrent second low
stage (DPHLPDOC2) is connected to the output SO1 (X110:14-16). This output is
used for sending a blocking signal to the relevant overcurrent protection stage of
the IED at the infeeding bay.

Figure 57: Directional earth-fault protection
Three stages are offered for directional earth-fault protection. According to the
order code, the directional earth-fault protection method can be based on
conventional directional earth-fault (DEFxPDEF) only or alternatively together
with admittance criteria (EFPADM) or wattmetric earth-fault protection (WPWDE)
or harmonic based earth-fault protection (HAEFPTOC). In addition, there is a
dedicated protection stage (INTRPTEF) either for transient-based earth-fault
protection or for cable intermittent earth-fault protection in compensated networks.

Application Manual
A dedicated non-directional earth-fault protection block (EFHPTOC) is intended
for protection against double earth-fault situations in isolated or compensated
networks. This protection function uses the calculated residual current originating
from the phase currents.
The binary input 2 (X110:3-4) is intended for directional earth-fault protection
blocks’ relay characteristic angle (RCA: 0°/-90°) or operation mode (I0Sinφ/
I0Cosφ) change. All operate signals are connected to the Master Trip as well as to
the alarm LED 2.

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 ABB 5SXE04-0146 3BHE004569R0003 5SHZ0860F0005 励磁系统控制
