ADE7752/ADE7752A
Figure 21 shows the connections of the analog inputs of the
ADE7752 with the power lines in a 3-phase 3-wire delta service.
Note that only two current inputs and two voltage inputs of the
ADE7752 are used in this case. The real power calculated by the
ADE7752 does not depend on the selected channels.
