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
Is This Answer Correct ? | 119 Yes | 45 No |
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)
Is This Answer Correct ? | 30 Yes | 20 No |
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.
Is This Answer Correct ? | 1 Yes | 3 No |
Answer / rajesh sutar
MF= CONNECTED CT/METER CT *CONNECTED PT RATIO/METER PT ratio
*space factor
(space factor =1)

An 11kv system consisting of an underground cable to a sub station about 300 meters away was shut down for about 10 hrs. On energising, it tripped off on earth fault about 10---20 mins later 6 times but since than it is not tripping.its already 3 weeks now. The SPAJ was found to be fine. what could be the cause.No test had been done to determine the cause of the trippings till now because of demand.
can u name the different types of motors used in different types of applications?
