how to calculate the no. of turns in secondary side of CT?

how to calculate the no. of turns in secondary side of CT?..

Basic trafo amp-turn is I1N1=I2N2
CT ratio 100/1 so I1=100, I2=1
in case of bar primary
N1=1
SO N2= 100*1/1 = 100 turns
in case of wound primary
N2/N1=100/1=100
so in this case we must have information about N1 primary
turns to find out Secondary turns of CT N2

BUT MY QUESTION IS WHEN A LOAD IS CONNECTED IN BETWEEN P AND N, THE LOAD CONSUMES SOME POWER AND THERE IS A DIFFERENCE IN NEUTRAL WITH RESPECT TO THE PHASE. THUS ACCORDING TO ME, THE ELCB WILL AUTOMATICALLY OPERATES WHEN EVER THE LOAD CONSUMES-- I KNOW IT IS WRONG. BUT THE SOLUTION IS?????????
