Calculate the apparent power in kVA for a 200 amp, 120/208 volt, 3-phase service.
Select one:
a. 769 kVA
b. 72 kVA
c. 576 kVA
d. 432 kVA
Homework Answers
In three phase service for line to line voltage , apparent power is given by
S(kVA) = √3 × I(A) × VL-L(V) / 1000
= √3 × 200 × 208 / 1000 = 72.053 kVA
And for line to nutral voltage , apparent power is given by
S(kVA) = 3 × I(A) × VL-N(V) / 1000
= 3 × 200 × 120 / 1000 = 72 kVA
So , the answer is 72 kVA
