Thanks to every one for suggestions.
My problem here is that the current transformer give me 10 mv AC, which will be 5 mv ac if i take only the positive side of it.
The output also it is a sine wave, so first i have to converted in DC , which will result in a pulsating 5 mv wave at 60 hz.
Then i have to convert that pulsating voltage in a dc line voltage, and in the final to use a comparator.
I tried to use a bridged rectifier for the 10 mv output and i got nothing, almost zero. I assume because the voltage is drooped across the diodes.
I read the page for comparators, but until i can use it, i need to get some kind a decent DC voltage to it.
Any suggestion ?
Best regards
Ion
