3-phase 3-wire wiring on the PW3337
QWhat is the difference among 3P3W, 3P3W2M, 3V3A and 3P3W3M when measurinng a 3-phase 3-wire circuit?
The 3-power-meter method is applied to 3P3W3M wiring, while the others (3P3W, 3P3W2M and 3V3A) use the 2-power-meter method.
[ 3P3W, 3P3W2M, 3V3A ]
Psum is the same for 3P3W, 3P3W2M and 3V3A.
Psum = P1 + P2
The difference is how to use U3 and I3 which is not used to calculate the Psum.
3P2W: Does not display U3 and I3.
3P3W2M: Displays U3 and I3 as the result of vectoral calculations.
3V3A: Measures U3 and I3 and displays the values.
