How to read Real Power using CS5460A with ATmega162

[saravananece82]

Hi,
Iam using ATmega162 for my AC energy meter project,
i can able to read the voltage and Current,but i dont no how to read or calculate the power can any one help me..
Thanks,
R.Saravanan.

hello,

I give you a link to a library published by C51, but the opcodes are the same and is a great job of "John D. Maniraj"

**broken link removed**

change, calls to your library SPI ... and the game is done

if you have any problems let me know.

regards

Hi,
Thanks.
I have seen the link, but in that there is function to calculate the real power.
I can able to read the AC voltage, AC Current, I am considering real power as Energy Register and able to get real power for resistive load, but my problem is when I connect the inductive lode (Motor) I am not get real power correctly…?
