5.2.1 Setting the Wiring Method
3P3W2M and 3P3W3M
The active power measurement results will be the same regard-
less of whether measurement is conducted by 3P3W2M (i.e., 2-
voltage, 2-current, 2-power-meter method) or 3P3W3M (i.e., 3-
voltage, 3-current, 3-power-meter method). When 3P3W2M is
selected, U3 and I3 will be calculated based on the U1, U2, or I1,
I2 measurements.
