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.
3.4.3 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 | PLC通信模块底座 TP854 3BSE025349R1 | | | |
