Power & Power Factor Measuring Accuracy
Accuracy Test, Wye Voltages
Step 1. Connect the current sources to the IA, IB, and IC current inputs
(5 A or 1 A, as indicated by the ITAP setting). Connect the voltage
sources to the VA, VB, and VC inputs in wye configuration. Refer to
Figure 7.3 on page 7.9.
