Conversion Theory

The momentary waveforms for phase voltages (U1, U2, and U3) are
converted into momentary waveforms for line voltages (u1, u2, and u3)
using the following operation expressions ("s" refers to sampling value).
u1s = (U1s-U2s), u2s = (U3s-U1s) , u3s = (U3s-U2s)

･

Following conversion, the two power meter method is applied.

･

Following conversion, the 9605-01 vector screen changes as follows. (Load:
