ELCB mean earth leakage circuit breaker,and it is the old
name of RCCB(Residual current circuit breaker, further ELCB
is voltage depended operation and RCCB is current depended
phenomena.and MCB is miniature circuit breaker which is
operated on thermal or magmatic effect of current.

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
