Question
how to calculate the multiplying factor for energy meter 
with CT ratio given
 Question Submitted By :: Electrical-Engineering
I also faced this Question!!     Answer Posted By  
 
Answer
# 1
MF= (main PT ratio x main CT ratio x meter constant)/
(meter PT ratio x meter ct ratio)
 
Is This Answer Correct ?    86 Yes 22 No
Sunil
 
Answer
# 2
Suppose CT ratio 100/5 then MF will be 20
then If you want to know the consumption so you
(Total Reading *MF)= Total Consuption
 
Is This Answer Correct ?    50 Yes 26 No

Answer
# 3
Line CT Ratio/Meter CT Ratio*Line PT Ratio/Meter PTratio 
Is This Answer Correct ?    31 Yes 8 No

Answer
# 4
M.F.= (Connected PTR/meter PTR) X (Connected CTR/Meter CTR) 
Is This Answer Correct ?    17 Yes 7 No
Sangamesh
 
Answer
# 5
If C.T Ratio is 150:5 Amp Than,
=150/5
=30
Now,M.F= 30*(Difference in meter reading)
It means if Previous reading is 11226
Current reading is 11626
Difference is 400 &
M.F=30*400
M.F =12000
 
Is This Answer Correct ?    17 Yes 8 No
Sukhdev
 
Answer
# 6
M.F= (CONEECTED PT RATIO/METER PT RATIO * CONNCTED CT
RATIO/METER CT RATIO)* METER CONSTANT
 
Is This Answer Correct ?    10 Yes 3 No
Naeem Zafar
 
Answer
# 7
M.F=(CT Ratio/Meter)* (PT Ratio/Meter)
(33/11)*(40/5)=?
like this
 
Is This Answer Correct ?    11 Yes 7 No
Ramesh
 
Answer
# 8
if given CT ratio is 100/5 than multiplication factor will be 20.should multiply with displayed kWh 
Is This Answer Correct ?    4 Yes 0 No
Ruksana
 
Answer
# 9
CT Ratio = CT RATIO OF CT*PT RATIO OF PT
-----------------------------------
METER RATIO OF CT*METER RATIO OF PT
 
Is This Answer Correct ?    10 Yes 7 No
J.p.
 
Answer
# 10
60/5 
Is This Answer Correct ?    4 Yes 7 No
