My instructor thought that as i'm trying to make law cost energy meter which also can give many other service in future like adding the remote metering to it, so i should use this 2 uC based energy meter, but as CT is very costly, like 30 dollar, why not i use a shunt sensor.
any way, I've little idea what my CT give as output. As you describe earlier, if maximum 10A goes through the phase, 1/40 of that current will come through the CT which is 0.25A right? Also as the avr465 uses 1:2500 Ratio CT which mean i need a shunt which can give .004A at the output when maximum 10A current goes through primary line? if these are correct, then my understanding with the shunt is zero. So, pleas help me in this part.
Finely, I want to built shunt with resistor at my home, so pleas tell me what are the are the elements do I need to reform this circuit . if possible, pleas add some calculation
