Answer Posted / shyam sunder thakur
The meter in this case can carry up to 40A current only as meter CT rating is 200/1,
Multiplication Factor if calculated is under
Adopted(line) CT Ratio X Adopted(line) PT Ratio
M.F =--------------------------------------------------
Meter CT Ratio X Meter PT ratio
200/5X11000/110
=----------------------------= 1/5=0.2
200/1X11000/110

hi everybody how to design string combiner box (scb) internal parameters like bus bar and spd (surge protection device and fuse which place to set that,and also bus bar one particular cross sectional how much heat generated and how much power loss tell me Clearly and briefly
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.
