3phase power meter using three AD7755

3phase power meter

Can I measure active and reactive energy and other parameters of a 3 phase power line by using three AD7755 in a circuit for each phase (3wire or 4 wire power lines)???

No

Why not? Please explain it.

 

[Nick_B]

You can't calculate FULL power
The phase information will be lost

Nick_B has right use AT73C501 as 3 phase convertor from A*T*M*E*L
best,

how can measure some power parameter such as flicker[/b]

 

[lutrue0410]

so that's mean the AD7755 cannot measure the power factor?
