yes above answers in context of not being open circuited are true.
But If the secondary impedence is not kept as low as possible(as during short circuit ), then there is a voltage drop across it , which result in a decrease in CTs accuracy.

explain why core loss of a transformer is almost constant under different load conditions when connected across a constant voltage and constant frequency.
I have 4 busbar of 1000 ampere. we use 4 busbar to make 4000 ampere in one phase.my problem is that when we applied 60% load on that then busbar produced high noise.what is the reason of that and how can i minimize that noise.

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.
mostly the questions were from machines... d.c. machines, transformer, synchronous and induction all theory paper........ few from power system... but the level of paper was easy.....
