Here is an adc project I did using pic. https://www.edaboard.com/threads/252959/

Now I am going to measure AC 220V without trf. I'm going to use a 220V AC to 5V DC transformerless power supply to interface with PIC ADC. The same thing I want to do with 440V. So I need a circuit (transformerless) which converts 1000V AC to 5V/12V DC. I will do the coding.
 

I need a transformerless power supply circuit which converts 1000 V AC to 5/12V DC.
 

As i understood , you don't need high currents , if so , why not a simple resistive voltage divider ?
BTW : do you need isolation ?
 

Isolation is not needed, but if it can be implemented then it will be better. Can opto isolater be used?
