3-Wire Network – 2 Current Sensors L1, L3 (Aron Method/Two Wattmeter Method)
The connections to the channels must be made as per the labels on the analog channel port
as shown in Section 3.5.
Note
•
Observe the polarity of voltage connection V1 (V1+ and V1-) and
current sensor I1 (I1+ and I1-).
•
The device does not correct the systemic phase shift of 30°
between phase-to-phase voltage and associated current; the
individual phase power values are calculated values and might
deviate considerably from the actual values. The actual three-
phase total power can be determined accurately using this
method.
•
This method is applicable only if IL1 + IL2 + IL3 =0, that is, if
there is no N conductor.
The following figure shows 3-wire network (Aron measuring circuit) connections.
