Dear all,
I am using external CT to measure Current parameter. I am using PIC16F1938 to measure analog . Now here i am looking for circuit and calculation involved to get proper current rating.**broken link removed**
Min Current : 0.8A
max Current :30A
Primary Current 30A nom., 75A max
Turns Ratio 1000:1
I have 10 bit resolution ADC.
Kindly suggest me the circuit how we can choose the value. I got article with Arduino . https://www.instructables.com/id/Simple-3-Phase-Arduino-Energy-Meter/
Let me know best circuit to be achieve better accuracy. Some forum recommend to use amplifier circuit . Let me know which is best
