Can i use voltage transformer with ADE7753 in energy meter application?

Question

Hi everyone, 
 I am designing electric meter with ADE7753, I use Current Transfomer and Voltage Transformer (VT) for Channel 1, 2 of &Aacute;DE7753 I realized that VT can cause 180 degree out of phase but ad7753 can only correct phase in -1.84 degree to 0.72 degree. So, can i use VT for energy measurement, and how? 
 I'll post my schematic below. Sorry for my english. 
 Many Thanks!

yes a VT can be used but you need to phase it correctly. If you are 180 out you need to swap the output terminal of the VT or CT 
 
 like this 
 
 You need to have the in phase with pf of 1 or positive energy at PF of 1
