Answer / s kannan

MF is not for panels for relays and meters only. Meters will be connected with CT and PT's secondary. If we want to calculate MF for meters like Voltmeter and Ammeter Just follow the formula Mf= CT Ratio X PT Ratio.
Eg:
CT Ratio: 600-300/1-1A(Adopted ratio is 300A as primary) PT Ratio: 33KV/rt3/110V/rt3/110V/rt3
Then MF:(300/1)X(33000/rt3/110/rt3)
(300/1)X(33000/1.732X1.732/110)
(300)X(33000/110)
(300)X(300)
90000
Means Multiply the particular meter's reading by this 90000 for obtaining the genuine value.
