• Vector Display When the Wiring System Is 3P3W (3V3A) (Three-Voltage, Three-Current)

U1(1), U2(1), and U3(1) are line voltages. I1(1), I2(1), and I3(1) are line currents.

By moving the vectors, U1(1), U2(1),

and U3(1), so that the starting points

of vectors are all at the origin O, the

phase relationship can be observed in

the same fashion as the 3P3W system.

(This instrument does not provide

a function for moving the vectors.)

• Vector Display When the Wiring System Is 3P3W (Three-Phase, Three-Wire)

U1(1), U2(1), and U3(1) are line voltages. I1(1), I2(1), and I3(1) are line currents.

However, U3(1) and I3(1) are not actually measured for the 3P3W system.

The vectors are displayed through computation.

and I3(1) are line currents.

The phase difference between the line voltages

can be determined from the phase difference

measurement functions φU1-U2 and φU1-U3.

φU1-U2

= This is the measurement function

φU1-U2.

φU2-U3= (φU1-U3) – (φU1-U2) – 180

φU3-U1= –(φU1-U3)
