The instrument is a single phase system. So you can analyse a three phase system
repeating 3 times a single phase analysis described in previous paragraph.
The Three Phase power values are given by:
Total Active Power = Pt = P1 + P2 + P3
Total Reactive Power = Qt= Q1 + Q2 + Q3
Total Apparent Power = St =
√(Pt 2
+ Qt
2
)
