hysterisis loss is the energy loss during the magentization and demagnetization of core material in each AC cycle.
During demagnetization, when magnetizing current reduces to zero magnetic flux will not goes to zero, further current is to be supplied in -ve direction to make it zero and the same in the magnetizatin process also. This losses collectively called as hysterisis loss.

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.
