SOURCE LOAD
①
②
3P4W wiring
①
When the U1 is selected as the PLL source
To measure voltage and current phase, the phase of the voltage of each
channel is shifted 120
°
. When the load is purely resistive, as shown above,
the phase difference of the voltage and current of each channel is 0.
Compared to 3P3W (3V3A) wiring, ch(2) and ch(3) are switched.
②
With an inductive load such as a motor, the phase of the current lags the
voltage.
