EEL 3216 Introduction to Power Systems Homework # 2 CHAPTER 1.8 and 2 1. A three phase wye-connected un balanced load is supplied by a balanced three-phase delta connected source. The three source voltages and two of the line currents are: V ab = 13.2 kV 90° I a = 19.42 A -33.1° V bc = 13.2 kV 210° I b = 16.34 A 189.3° V ca = 13.2 kV 330° a) Find the neutral current I n and the phase-c line current I c b) Find the impedances Z an , Z bn , and Z cn c) Calculate the active, reactive, and apparent power delivered by the source d) Draw the phasor diagram of all voltages and currents 2. (Problem 2-2, p 79 in Textbook) The circuit below (Figure 2) shows a three-phase
