Answer Posted / krishna bagavan
for a transformer, ratio of primary voltage to secondary voltage is equal to ratio of primary turns to secondary turns ie ... v1/v2=n1/n2 ,then v2=v1n2/n1
v1 is incoming or system voltage on which we depend upon & we can not change.now the variables are either n1 or n2 to get required secondary voltage. comparably primary turns are less and it requires less insulation level to change the primary turns,so providing tap changer on primary is better option.
similarly v1/v2 = i2/i1, ie v2 = v1i1/i2, here also vi is system voltage,i1 and i2 are variables. comparably i2 is always higher side and changing primary current with available insulation level is easy,and providing tap changer in primary is the option.

I have one ct of ratio 3000-2000/1 Amp its knee point voltage mentioned on name plate is 500-333/30mA-50mA at Vk/2. in secondary box there is three terminal named 1S1, 1S2, 1S3 then on which terminal obtained the knee point voltage ie 1S1-1S2 OR 1S1-1S3 & also specify the knee point voltage for the ratio 3000 from name plate.
