Using CT with ADE7758

Hello all,

I am working with ADE7758. Uptill now I can successfully read VRMS & frequecy with the IC.

Now I am trying to read IRMS. I have two types of CTs with me.

One with turns ratio as  2500:1(PCB Mountable) & the other one with ratio 100/5 A(Very Bulky, not PCB Mountable)...

Has anyone tried to use second CT having 100/5A ratio.

For using second CT, we will need to have burden resistor less than 0.1 ohm. But the connecting wires from CT to PCB will itself add more resistance. So is it really possible to use second CT with this IC?

Thanking You in anticipation...
