current (IL) is 16A at 0.8 power facter,
answer option Roivodo
A. 15. 2 kVA
B. 11.5 kVA
c.) 9.2 kVA
D. 5.3 kVA​

Answer 1

Answer 2

Answer:

apperent power is option 2 )11.5kVA

Explanation:

Given that, phase voltage (Vph) = 415 V

Line voltage (VL) = √3 × Vph

Line current (IL) = 16 A

For a 3 phase star connected system,

Apparent power 

P = VL×IL

=√3×Vph×IL

= √3×415×16

=11500.81 VA

=11.5 kVA

therefore Apparent power 8s 11.5kVA
