Hi all,
I have a current transformer, and I whant to read the value using the ADC of a 16F873.
Problem is, for 20A in primary, I get 20mA on secondary, an with a resistor of 100Ohm I get a sine wave of 2.828 peak.
I have tinked to put a rectifier bridge of schottky diodes, but any way, when I get 1mA, the voltage are all droped on diodes...
Some sugestions?
