3.4.3 Functional diagrams
The functional diagrams describe the default input, output, alarm LED and functionto-function connections. The default connections can be viewed and changed with
PCM600 according to the application requirements, if necessary.
The analog channels have fixed connections towards the different function blocks
inside the IED’s standard configuration. Exceptions from this rule are the 12
analog channels available for the disturbance recorder function. These channels are
freely selectable and a part of the disturbance recorder’s parameter settings.
The analog channels are assigned to different functions. The common signal
marked with 3I represents the three phase currents. The signal marked with Io
represents the measured residual current via a core balance current transformer.
The signal marked with Uo represents the measured residual voltage via open delta
connected voltage transformers.
The EFHPTOC protection function block for double (cross-country) earth-faults
uses the calculated residual current originating from the measured phase currents.
3.4.3.1 Functional diagrams for protection
The functional diagrams describe the IED’s protection functionality in detail and
picture the factory set default connections.

Figure 12: Overcurrent protection
Four overcurrent stages are offered for overcurrent and short-circuit protection.
The instantaneous stage (PHIPTOC1) can be blocked by energizing the binary
input 1 (X120:1-2). Two negative sequence overcurrent stages (NSPTOC1 and
NSPTOC2) are offered 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 described protection function blocks.
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.

Figure 13: 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). 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.
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.
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 double earth-fault
protection operate indication.

Figure 14: Residual overvoltage protection
The residual overvoltage protection (ROVPTOV) provides earth-fault protection
by detecting abnormal level of residual voltage. It can be used, for example, as a
nonselective backup protection for the selective directional earth-fault
functionality. The operation signal is connected to alarm LED 3.

Figure 15: 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, | | |
