Can I measure the voltage at 220ac using adc9153a?

I am trying to use ADE9153A.

The purpose of the ADE9153A is to:

1. Active power measurement

2. 220 AC PT measurement

My question is as follows:

1. In the example circuit using a CT sensor, the current is input to IAP and IAN. No other circuits are visible. How do I measure active power with only CT current?

2. I want to measure PT and voltage. Can I use the ADE9153A to measure the voltage on AC L and N lines? I wonder what will happen.

Thank you for reading my question.
