what do you mean by mf of energy meter & its formula?

Answer Posted / virendra

MF means the Multiplying factor.

Its nothing but the CT ration . as a big amount of the
current to be measured So direct Metering is not possible
hence CT operated meter is used

Formula :- if the CT ratio is 60/5 then metered reading
should be multiply by 12 which give the exact Power usage
