I will be attaching the complete circuitry, in which,
i think they intend to pass 1A....through the input. Now I understand, a picture is worth a 1000 words.
But....THey have mentioned 1:1800...which means if they pass 1800A
in input of CT then they will get 1A at CT output.
But...Imax is 40A....so CT max output is 40/1800 = 0.022A.
Am i right? Yes
If i pass 22mA through my current source,
then, i will get 314mV accross my ade7754.
And the 0.5 is the maximum(must not be given..some head-room should be there.)..
and they have specified...355mV.(giving some factor of safty).
So it is all clear now....So if i need to simulate the current, then i must vary the current(from my current source). from 0-35mA.....this will be equivalent to simulating current in the line(whatever the range may be it depends upon the CT).
Kindly confirm my approach. Looks good to me
