Three Phase Current Transformers

11/30/2010 1:39 AM

as such we have three phase power transformers, why cannot we have three phase current transformers and three phase voltage transformers? why connect a separate current transformer for each phase? is there any possibility of designing of a three phase current transformer.

Separate CT's and VT's give more flexibility when mounting on busbars etc. Three phase units do exist where the phase spacing is fixed, for example on the outgoing connections of a switch. Here is a typical one, many others exist:-
