We chosen ADE7880 for Three phase static meter application and we plan to use 2500 turns current transformer (CT) for R,Y,B Phase current measurement. Also we want to measure Neutral current,

Can we use same 2500 turns phase CT or low turns CT enough for neutral current measurement?

Please suggest neutral current CT require turns ratio

Meter Input Power:

1) Phase voltage: 240VAC ; Vmax = 288VAC per Phase

2) Imax = 120A AC
