Answer / sunil kumar das
MF=PT Ratio x CT Ratio
Ex: PT ratio= 33KV/110V
CT ratio= 40/1A
so please this value in formula
MF: 33KV/110V x 40/1A = 12000

To calculate MF(multiplication factor) we must know current
transformer ratio and meter ct ratio
mf = current transformer ratio/meter ct ratio

Answer / mohamed ali.m
Hi,
this Correct Ans,
MC = PT Ratio x CT Ratio x Dial Constant/ Meter PT Ratio x
CT Ratio
For Exmple : 100x60x1/1x1 = 6000( This MF)

Answer / ripun
Mf=field ct ratio/meter ct ratio *field pt ratio/meter pt ratio
Let field ct ratio=15/5a
Field pt ratio=11kv/110v
Meter ct ratio=-/5a
Meter pt ratio=-/110v
M.F=15/5*1100/110=300
| Is This Answer Correct ? | 21 Yes | 15 No |
Answer / chandu
multiplication factor is depending upon CT Ratio Thats o.k
but if meter constant is given what will be the
multiplication factor for 600/5 CT
| Is This Answer Correct ? | 8 Yes | 4 No |
Answer / er l r daroch
Line ctr 50/1a
Meter ctr 50/5a
Is it a right combination
| Is This Answer Correct ? | 4 Yes | 5 No |
Answer / sureshmuthusamy
MF = External ct ratio*external pt ratio/metering ct ratio* metering pt ratio(if there)
= 40* (110000/110)/1*1
= 40*1000
=40000kw
= 40w(40000/1000)
so,MF is 40(your daily tariff meter consumption (kwh)*40= consumption /day.

Answer / rajesh sutar
MF= CONNECTED CT/METER CT *CONNECTED PT RATIO/METER PT ratio
*space factor
(space factor =1)
