Quick Reference Guide for PowerXplorer / Power Guide / Power Visa

pg 10

3 Phase, Four Wire Wye

Channels A, B, and C are connected to voltage and current probes. The neutral is
connected to common and is the reference for the three channels. The figure also shows
voltage connection using channel D as a differential input for measuring neutral to
ground voltage. Neutral to ground measurements are important but optional.
