Hi
I want to measure the current in line. I want the sample of the current. I used a low power rating transformer as current transformer. As the secondary is HV side, my digital circuit may damage due to high voltage. I attached a circuit here. Can i directly connect the transformer to my electronic circuit? Or should i use any isolators?
And what is the value of resistor R. I just need the range of the resistor.
My digital circuit operating voltage is 5v. can any body help me?
