Answer Posted / pradeep

Regarding answer 11, i think in case the Neutral to Earth
voltage is high, it means there is an unbalanced load in
the three phases (in case of 3 phase supply) or the neutral
is not proper. Either way, there is a chance of current
flowing back into the circuit because of improper neutral
or earth not properly grounded, resulting in equipment burn-
outs in case of a surge. These equipments need not be
switched on and will burn-out in case of fault. Thus it is
recommended to keep the voltage between Neutral and earth
as low as possible.

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.
