Answer / pankaj

It means 100A for primary, 5A for metering & 5A for
protection

Answer / krishna chaitanya

this type ct is 2core ct one is useing protection and
another one is measuering generally we are see one core and
two core ct's now three core type ct's also avilable

Answer / suthan prabhu

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
