See attached for problem.
Part a) of the question asks to find the complex power of the combined load. Following is my attempt at the answer.
1. Find complex power for load 1.
S1=\(\frac{|Vl|^{2}\sqrt{3}}{Z^{*}}\)
S1=\(\frac{840^{2}\sqrt{3}}{30-j40}\)
S1=14.665+j19.554kVA
2. Find complex power for load 2.
S2=P+jQ
S2=48+j48tan36.87
S2=48+j36kVA
3. Total Complex Power
S=S1+S2
S=62.665+j55.554kVA The answer is 56.47+j47.29kVA.
