Energy meter using ADE 7763

[aravindmgcee]

Hi,
I am trying to do an single phase energy monitoring project. The voltage and current I want to measure is 240Vrms and 20A rms respectively.
I am planning to use a voltage divider for voltage measurement and ACS 712 -20A for current measurement . Micro controller planning using is pic 18f series. Energy meter Ic planning to use is ADE 7763.
But i have no idea about how to design circuit of energy meter( i am at level 0 at energy meter). So please provide me with circuit diagram of energy meter using the components and specifications given above.


thanks in advance....

At microchip.com there is a energy meter project.
There are examples on using ADE7763. You might look at the ADE7763 evaluation board.

Can i use acs 712 as current sensor in energy meter using ade 7763?

 

[ronsimpson]

YES

A current transformer also works.

YES

A current transformer also works.

thaks
Could you please help me by giving the c- code for energy meter ??

What will you do if all is given to you?

Not quite "all".

A PCB design would be nice, too.

If acs 712 can be used,please tell me how it can be connected to V1P and V1N pins of ade 7763??? Output of acs 712 is from its pin no: 7 ..i think it can be connected to V1P of ade 7763... bt what to connect in V1N of ade 7763??

The ACS712 has an output voltage of 0.5VCC, meaning the output voltage swings from 0.5VCC to VCC at positive currents and from 0.5VCC to zero at negative voltages.

Check the ADE7763 datasheet if it can work with those values. If necessary you must add a signal conditioner making the two parts suitable to measure AC current.

Of course I will do that - if you push my chair.
