ECE 430 homework assignment #2 (In class quiz – Thu/Fri, Sep 11/12) Text problem 2.16 (partial answer: I line = 1,255Amps, P+jQ tot = 600 +j450 MVA) Text problem 2.17 Text problem 2.19 Text problem 2.20 Text problem 2.25 Special problem #1 A balanced, 3-phase, 3-wire, 60Hz, Wye-connected source is serving a combination of balanced loads in various configurations. Measurement of the source line voltage indicates 480 Volts (line to line). Measurement of the source line current indicates 23 Amps. When 8 KVAR of capacitance (3-phase) is added in parallel to the other loads, the source voltage stays the same and the source line current changes to 18 Amps. What is the total 3-phase original load in Watts and Vars? (Partial answer: 14,153 Watts) Special problem #2 The following three-phase, balanced loads are connected across a three-phase, wye-connected

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
