What is the best way to measure main voltage with isolation

[andrew_]

Hi,
this is my first post.
I would create an AC triphase voltage mesurement. I'd prefer do not use trasformers because i would create a small object but i'm really in troubles because I don't know how.
I would read the voltage in continuous way with microprocessor (a/d input).
Someone can help me with good ideas?
Thanks,
Andrew

The best way to measure high voltage is depend upon application requirements such as common mode rejection, bandwidth, voltage isolation, voltage measurement range, accuracy, operating temperature, size of voltage sensing device, etc. The following is a list of links for your reference.
