Answer / pankaj rana

The no load voltage is greater than full load voltage.This
effect is called as Ferranti Effect.This effect is due to
the voltage drop across the line inductance,due to the
charging current ,being in phase with the applied voltage at
the sending end of the line.Thus both inductance and
capacitance are necessary to cause this effect.The
capacitance therefore the charging current is negligible in
short lines but significant in medium and long transmission
lines.

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.
