PROBLEM 2 (BALANCED THREE PHASE CIRCUIT) Consider the circuit below. The source voltage amplitude is 10.0 kv. The load per branch is 300 n. Assume that the transmission line nce is negligible. 082,428 v 773 5 Load 10 kv 300 30on 19.240A Determine: a) RMS source voltage b) Line-to-line voltage amplitude v ST PT t GT PT 10 PT c) Line current amplitude d Source current amplitude 333.3 KVA X e) Per-phase load voltage Per-phase load current J) Power loss occors when g) Total real power generated h) Total reactive power generated You nove reactenner. In this i) Total complex power generated j Total transmission line power loss curse, you dont nerve on A f) In y ,Tine IL line ICA TL 9.245A 773.5) 19,245 A cos 6 333.3 Kw

Explanation / Answer

a) 5773.5 is itself an rms voltage

d) Ia= sqrt(3) *IAB = > IAB =VAB /Z(delta)

                                     Ia= sqrt(3) * 11.11= 19.24Amps

g and i) complex generated from source= S= P+jQ

                                                            S= 3Vab* Ia^2

S= 11105328VA

and P = 11105.328kW
