The semantics for these parameters:
Magnitudes are the scaled RMS value of the voltage or current. In Wye and split-
phase modes, voltages are reported as line-to-neutral. In Delta modes, voltage is
reported as line-to-line. Phase angles are referenced to Phase 1 Voltage, which is
defined as zero, consistent with the 4-quadrant metering diagram included in
Power Metering
on page 87.
Current angles in Delta modes include a 30° offset due to the phase angle
difference between Wye and Delta modes as shown in the following diagram.
