APPLICATIONS INFORMATION
The voltage and current waveforms of a polyphase system are
defined in the following equations:

To understand how these signals relate to each other, create a
phasor diagram following a convention using lagging phase angles.
Figure 83 shows a common polyphase metering configuration,
the 4-wire wye, with VA, VB, and VC. Phase B lags Phase A by
120°, and Phase C lags Phase A by 240°. Currents are shown at a
power factor of 1, PF = 1, where θ = 0 in the expressions for IA,
IB, and IC, and the current is in phase with the voltage.

Figure 84 to Figure 87 show common metering configurations:
3-wire delta, 4-wire delta, and 3-wire residential and network.
The ADE9078 can also measure multiple single-phase circuits.

The phasor diagrams show how the voltages and currents are
related in time. Figure 88 shows the 4-wire wye voltage phase
sequence in time, corresponding to the Figure 83 phasor
diagram and equations for VA, VB, and VC, provided previously
in this section.
