3.7.3 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 summation connection of the phase
current transformers.
3.7.3.1 Functional diagrams for protection
The functional diagrams describe the IED’s protection functionality in detail and
picture the factory set default connections.

Figure 38: 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.
The upstream blocking from the start of the overcurrent second high stage
(PHHPTOC2) 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.

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
function offers different operating modes associated with the circuit breaker
position and the measur | VMIVME-4140 电路板主板全供应PLC系统 | | | |
