Now that this is actually coming together, I have a followup question:
The tap above is 1v, then going through a 100k resistor then in line with the CT and the ADS. This is to offset the incoming negative voltage to minimum of 0V in the case that it will never drop below 0V (GND).
- Do i understand that correctly?
- If that is the case, let's say I put a PZCT-02 to J2 (diagram above) it has 1000/1 ratio and 10 Ohm burden resistor built in. According to "Irms = (((voltage / 2.0) / resistor) * Turns) * 0.707" Irms = 34.5amps. I am assuming voltage is 1V because that is the most I can offset. Am i understanding that correctly? or do I still go off of the ADS voltage of 3.3v? which will be ok for my application? I am measuring MAX of 65 Amps
