Homework Statement
The power consumed by 2 3-phase parallel loads are:
Load 1: 12 kVA with power factor 0.7 lagging
Load 2: 8 kW with power factor 0.8 lagging
A)Find the complex power consumed by Load 1 and Load 2.
B)Find the total complex power consumed by these two loads
C)Determine the combined load power factor
Homework Equations
S = V * I*
S = sqrt(P^2 + Q^2)
P = V * I
The Attempt at a Solution
A)
Load 1: Q = 12kVA, cos(θ) = 0.7, sin(θ) = 0.71414284272
S = Q/sin(θ) = 16803.36VA
Load 2: P = 8kW, cos(θ) = 0.8
S = P/cos(θ) = 8kW/0.8 = 10000VA
B)
Total Complex = S1 + S2 = 26803.36VA
Am I doing this correctly?
