hi friends,
I want to measure current consumed by a 3-Phase 220v motor. I can do AC current measurements using CT(Current transformers) but i just want to know do i need to install only one CT or do i need 3 CT's one for each phase. What calculations are involved in finding out the net result.
Is it :- Itotal = (Sqrt(3)) * Iphase
Thanks in advance.
With best regards,
Garg
