A three-phase generator is connected to a strong grid with line-to-line voltage 14 kV and frequency 50 Hz. The generator is rated at 15 kV and 180 kVA. The resistance in the windings is 2 Ohm/phase and the reactance is j3 Ohm/phase. The current in one phase was measured to be: I= 1500 / -25º A.
What is the line-to-neutral voltage of the generator, |Ei|=____ kV.
Hi, I've got issues understanding what I should calculate and what "Ei" actually means?
I tried to calculate the I(phase)*Z(polar) to get the Ei(line-to-neutral), which gave me 5408,32V. Which is wrong. Then I tried to take the V(line-to-line)/sqrt(3) to get Ei, which gave me 8082V which is also wrong. How am I supposed to do it?
