3.9.2.2 Default disturbance recorder settings
Table 42: Default analog channel selection and text settings
Additionally, all the digital inputs that are connected by default are also enabled
with the setting. Default triggering settings are selected depending on the
connected input signal type. Typically all protection START signals are selected to
trigger the disturbance recorded by default.
3.9.3 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 and 3U the three phase voltages.
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.

Application Manual
The EFHPTOC protection function block for double (cross-country) earth-faults
uses the calculated residual current originating from the measured phase currents.
3.9.3.1 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 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.
