calculate multiplication factor of a trivector meter with line ct ratio 200/5A, line PT ratio 1100..

Answer / 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

calculate multiplication factor of a trivector meter with line ct ratio 200/5A, line PT ratio 1100..

Answer / k.prakashchandra

If the line CT were of 200/1 ratio, the meter would read
correctly. As the ratio is 200/5, for 200 A primary current
the sec current will be 5 A instead of 1.0 .Hence you have
to divide the reading by 5 ,if it is capable of taking 5A.

Answer / ajaz kirmani

Multiplication Factor MF = [ (200/1)x(11000/110)]
-------------------------------
[ (200/5)x(11000/110)]

MF = 5

Answer / jaskanwar

In a CT PT connection if there is a LTCT meter of 200/5 installed instead of HT meter of -/5 A . Then what will be the MF for this situation.
CT PT = 10/5 A
