Hi ,
I need to measure voltages of all three phases and to calculate line voltage,phase loss,phase imbalance in a 415 v,50hz,3 phase delta connected system.It will great help if anyone helps me to measure it using microcontroller based cicuit.
Regards,
Tamil

Something like this is what you need, but you'll need to measure your voltages to neutral, (and derive an artificial neutral if you don't have one), because without that, the phase relationship of the L-L voltage and line current will be wrong, hence you won't be able to measure power.

Robert, your link doesn't seem to work.

It does - now. Thanks. (Spurious characters in front that fooled the Drupal parser, I think.)
