Answer / azhar
cable size is calculated depending up on load ..for example
1 kw load takes 1.8 amps current..if the load is 5kw..than
9amp is the current for amp current the selection cable size
can be opted on the basis of manufature detial like
havells,polly cab..have the range of cable for certain
amount of current we have to selected the cable size on the
basis of manufacture range sheet

As we know multiplicity factor derivation equation is as below MF = main c t ratio / main p t ratio * meter c t ratio / meter p t ratio * meter dial constant Where in digital meters for HT kwh import export now a days meter constant are calibrated already which is 1 So my question is For HT 11kv 110 v line values are as below Main c t and p t ratio are 11000 v and 110 v and 20/5 means 20 amp and 5 amp Now meter values are 11000/√3/110√3 and primary and secondary amp are displayed as -/5 amp on kwh meter so what will be the MF for this meter ?
