why secondary terminal of current transformer should not be
open circuited?
Answers were Sorted based on User's Feedback
Answer / narmatha
if secondary terminal is open circuited then due to absence
of counter amp-turns of the secondary,the unopposed primary
m.m.f. will be set up an abnormal high flux in the core
which will produce excessive core loss with subsequent
heating and high voltage across the secondary terminals.

Answer / pritesh
if we put ct secondary open circuited than no current will flow through it and also there will be high voltage across it which will damage it

Answer / rahul
A CT Current transformer) is used to reduce the high current on primary for measuring it with small range instruments. So its number of turns on secondary will be high. So if we open circuit the secondary it will results in very high voltage on secondary which in turn damage the CT.

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.
