Preliminary Technical Data
Figure 21 shows the connections of the ADE7752B analog
inputs with the power lines in a 3-phase 3-wire delta service.
Note that only two current inputs and two voltage inputs of the
ADE7752B are used in this case. The active power calculated by
the ADE7752B does not depend on the selected channels.
