3 phases Ac Current to 4-20 mA converter

Hi guys:

I've been looking up on the web but I can not find exactly what I'm looking for.

I need a 3 phase ac current to 4-20 mA converter for 14 existing and working motors:

7 motors 50 KW @ 460 VAC
7 motors 40 kW @ 460 VAC

I do not want individual current transformers, one for each phase. I want a device that has to be installed underneath contactors and three phases pass thru the device and as a result I got a 3 phases current average in 4-20 mA format, no problem if I got three 4-20 mA signals one for each phase. The device can be powered by ac or dc.
My two cents.
