calculate multiplication factor of a trivector meter with
line ct ratio 200/5A, line PT ratio 11000/110V and meter CT
ratio 200/1A and meter pt Ratio 11000/110V.
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
