TA transformers as analog inputs?

Hi!

I would like to use arduino to record the power supply to the loads.
For doing this I was thinking about connecting the arduino's analog inputs to TA transformers (the ones directly linked to the cables of the loads).
Is this possible? (I guess yes)
Which are the current and voltage limits that arduino can handle?
Does the transformer have to transform the current in DC, or is it fine in AC?

Thanks

The Arduino can "handle" voltages on input pins between 0 and 5 volts. For practical purposes, the inputs draw no current.

What are TA transformers? What power supply, and what loads?

Ta transformers are current transformers like this one:

I would like to record the consumption of generic loads (like a fridge, oven...) connecting that transformers to arduino's analog input.
And I was wondering if it's possible.

Thanks
