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

We know that primary transmission is done to reduce current so that i^2*r loss could be minimised but according to ohm's law v is directly proportional to i,which indirectly means higher potential difference means larger current?so how the current is minimised in high power transmission line??
