Analog channels with 9 matching transformers and 9 sensors
Depending on whether sensors are included or not, REF 54_ feeder terminals have
9 (without sensors) or 10 (with sensors) physical analog channels (see table below).
The number of channels used depends on the feeder terminal configuration and the
kind of matching transformers or sensor inputs used. Furthermore, the feeder
terminal includes virtual analog channels (refer to Section “Calculated analog
channels” on page 42) for calculating the neutral current, phase-to-phase voltage
and residual voltage from phase currents and voltages.
Each analog channel is separately configured with the Relay Configuration Tool.
Both the measuring unit for each analog channel and the type of signal to be
measured are to be configured.
