Hi hmani.

Now I'm very clear about current measurement.

Another thing that I want to ask you is:

Currently in our application we are using two current sensor because the source is 220VAC but the load is divide in two of 120VAC (the neutro is on the midle) and in fact it is unbalance load then we have to take the Energys mesurement and add EnergyA plus EnergyB. And my question is:

The ADE7953 measure:

PowerA = Vin * Ia

PowerB = Vin * Ib

or

PowerA = (Vin/2) * Ia

PowerB = (Vin/2) * Ib

Actually this point is not very clear in datasheet. which voltage use to calculate PowerA, PowerB, EnergyA, EnergyB.

Best Regards

Alejandro

Hi Alejandro

The power calculation is done by multiplying voltage and current signals. The active power is VIcos(theta), reactive power is VIsin(theta) and apparent power is VI, were V and I stand for the voltage and current RMS values.

So in ADE7953, each of the current channels is multiplied with the voltage channel inputs and follow the signal chain as stated in the datasheet under the Active power calculation and reactive power calculation section.
