If Va0, Va1, Va2 are sequence components of Va and Ia0, Ia1, Ia2 are sequence components of Ia, then total 3 phase power P is given by
A.
P = Va0Ia0 + Va1Ia1 + Va2Ia2
|
B.
P = Va0Ia0 + Va1Ia1 + Va2Ia2*
|
C.
P = 3(Va0Ia0 + Va1Ia1 + Va2Ia2)
|
D.
P = 3(Va0Ia0 + Va1Ia1 + Va2Ia2*)
|
Answer : Option D
Explanation :
There are a total of 9 components (Three for each phase). Moreover, in general, P = VI*.
