Hi
I have been working on Energy meter ADE7758 interfaced with Pic18LF8722, can anybody help in calibrating Energy and power factor. Im able to read Current and Voltage on each phase properly.
Thankyou
Ravi.

I'm interested to know more about your project. I've been wanting to build one for myself too.
Anyway, I found this website which posts some stuff on DIY watt meter.
I don't know if that helps.

Hi
I made a multi transducer with this energy meter ,
may be i could help you if you say details of your problem.

i am also working on an energy meterusing ade7758, but i am not able to understand how to calculate RMS voltage after reading the RMS voltage register.
can anyone help me? same for current RMS also

hi
you shod divide the reading form rms register to full scale of register then mult the result with maximom of your voltage or current.
for example max voltage of your circuite is 300v ( as vmax)
full sacle of v register is "1d38..."(use datasheet)(as fsc)
reading of register is "34d" as (vre)
result=vmax *(vre/fsc)

hello
the calibration of the voltage and Current which not leads u to accuracy. Go for Phase calibration for calculating the instantaneous Three powers.
The file what i attached may useful for u. Let me know ur doubts and feedback. if ur facing problem still.

I have tried to work with this chip ADE7758 but have failed in each attempt. I tried to make chip talk with the MC68HC11, PIC28, & FPGA. MC68HC11 was the worst one, where the programing was the matter. PIC28 - I fried this one the first time. And the FPGA - I did succeeded with the programing, but here the chip was not getting caliburated with the output, where I am getting repeatedly 'FFFF' in the 7segment output.
Hence, I request any of them who know or have done their project to come forward and help, regarding this failur that I have faced.
I will appreciate your help, feed back or even I will buy/pay for your time or the whole project.
Feel free to email at pm_kle(at)yahoo.co.uk
thanks

Hi oneshotnike.
Here with i attached the file for interfacing the ADE7758. Go through with this. i didnt complete the Full
interfaced.
