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
