Not Necessary, Like in Siemens Siprotec Relay we can change the CT star point. There are two options, towards the time or towards the busbar. So however your CT star point is in the field you can configure it in the relay.

what happens when ac supply is given to D.C motor.
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
