he 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.
3.8.3.1 Functional diagrams for protection
The functional diagrams describe the IED’s protection functionality in detail and
picture the factory set default connections.
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.

Figure 46: 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 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
