Answer / raj

If you use all 3ph ( R,Y,B Core of Cable ) for single phase
load then only unbalanced current will flow through neutral
(1/2 Conductor ) but we must try to balance current in all
R,Y,B Phases.If you have to use only one single phase
circuit then use R+Y for Phase and B+Black for neutral (
Use twin Core to get more rating outout ).

we all know that in transformer, voltage and current are inversely related i.e. Vp/Vs= Is/Ip....so in standard CT..we have a ratio of 200/5...that means our voltage should increase by ratio of 40..althoug that is not the case...because that requires high insulation level.and pratically not feasible......can anybody clarify my ques.......thanx
