Hi,
I have CT with below specs:
Primary Current: 100A, Turns ratio: 2500:1.
Solid core and PCB Mountable type.
Link: https://www.electrohms.com/product-ct1273-a1-rc
I'm trying to measure 60W Bulb current consumption using arduino.
I have followed this reference example:
with the burden value of 42 Ohms since in my case, for 100A input primary CT will generate a secondary of 40mA.
I tried to run the code. But I'm returning with a random value when bulb is off, current is showing 2.02 and when I turned bulb on it shows 1.85.
Could any one please help me with what I'm doing here?
I've used the same code.
