what is the meaning of knee point in current transformer and
how to calculate?
Answer Posted / searchvineet
every measuring type or protection special current
transformer comes with a ratio of there Ip/Is [Ip=current in
primary Is means current in the secondary] which generally
means how much minimum current you are injecting in the
primary and with respect to that how much you are getting on
the secondary.Lets say 100/1 means 1amps in secandry for
flow of 100 amps in primary.
know lets say if u inject more then 100 amps in the same CT
say 200amps what will happen??????
So the Answer for understanding the Knee point is above .
There is a level of sustaining in the CT up to which it will
work perfectly fine beyond that limit or after that limit it
will behave abnormally and there is a point came after which
it Will SATURATE that level is called as the knee point

I have a current transformer with 1 main reading meter with transformer outside the building and a control panel having 5 CT reading meters with black round coils inside the building. I want to know, A) when current pass through the Transformers, will the current be reduced or be the same and after that B) when current pass through the CT meters with black round coils, will the current be reduced or be the same. C) in the above process will the reading of the main meter be same or different, from the total reading of all the 5 CT meters.
