Current Transformer
(OP)
Hey guys ! Assume there is a balanced 3 phase load drawing 5A in each phase. If we attach a measuring CT around any one phase then it will show 5A. If we thread all the 3 phases through the CT, it will show 0A. What will it show when we thread only 2 phases through the CT and why ?

Half full - Half empty? I don't mind. It's what in it that counts.

They are both 120 degrees out of phase and if you add them vectorially, you get a single phase current that has the same magnitude as the third phase and is 180 degrees out of phase with it.
