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 ?
