I have to measure the current which will be around 1.3miiliamp.
what i did was used a 80/2 split core ct and inserted the phase wire into hole of ct and increased the number of primary turns into 3,so the flux induced on core was three times the current flow.On secondary i was able to detect the flow of current using a multimeter.the measured value on sec was .0012amps.To find phase current i calculated as ((.0012/3)*40) and the value is .0133amps ie,13.3milliamps which is far differing from 1.3milliamps.
Is my way of doing is right?
