Parameters shown are in ohms per phase 7.2 A synchronous generator rated 10 MVA, 35 kV, three phase, 1800 rpm has synchronous reactance xs = 12.0 ohms / phase. The DC field current is adjusted to obtain an open circuited terminal voltage at rating. Then a wye connected load is connected to the generator and that load is 100/30o ohms per phase. (A) Find the stator current magnitude.

    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.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    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.
