Hi,
I want to make a circuit which measures:
voltage(ph-ph and ph-n)
current (each phase and current of neutral)
Frequency
Cos fi
.
.
.
and if possible THD.
Is there any chip that measures these parameters from 3phase wire and give me the result digitally in order to connecting to micro controller(such as avr).
measurement of current will be via 3 CT's with x/5 A.
Regards,
