Dear sir/madam,

I have attached file having power samples at load points voltage=240v and current = 5A and pf = 0.5Lag ..

my question is i want to reduce this variation having maximum value is 60300W ..and minimum to 60080W .

Can i reduce this fluctuation to middle value to 60190 having least variation...

Hi Satish,

It looks like your results are influenced by sinusoidal noise. Can you share your AFE circuitry? Do you have low pass filters?

Thanks,

Mitch

Dear sir,

Thanks for your reply..

But sir I want to reduce it from software end...

Is there any process to do this...and reduce the noise to the range described above..

Or to some level to software end..

Hi Satish,

Sorry for the delayed reply.

You could implement a SW filter to try to reduce the noise, but I want to make sure that you have the proper hardware implemented. Can you compare your AFE with what we have in our reference design? Please see the link below:
