How to measure the IxIxt (current X current X time)?

[iberia]

measure i2t

I all,

I need a schematic for measure the current on transformer of intensity.

I use 1 ADC but I need to convert the voltage RMS to VDC.


My problem IS:

I need measure the IxIxt (current X current X time)
Best regards

Is your ADC measuring the current???
Is your ADC enoght fast to your application???

Geting many samples of your ADC, you can solve making the integration of all your samples:


................#of samples
...............____
i2t=(.........\........i * i ) * delta t
................/___
................n= 1

Where: delta t is the time beetween samples
i is the current measured in each sample
