Thanks a lot for your reply! I think I understand what you are saying. So, you do have zero sequence and negative sequence voltages created by unbalanced currents in the generator? Is that right? And if yes, would you know how they actually create this voltages? You some things about the mmf in...

Sadly, It is not what happen. I saw more exercises like this one (LN fault) and the phase voltages do change, a lot. But still don't know why kkkkkkk. Pretty interesting stuff. If someone has any idea why, it would be very appreciated

Hello, I'm a very slow learner! I try to understand every piece of the information that is given. And recently I was solving some problems involving symmetrical components and I couldn't figure this one out: -The neutral is solidly grounded. -Phase B and C are open. -You're shorting Phase A...

I'm sure you are all familiar with calculating the inductance of a long transmission line. We first calculate the partial self inductance and we add to the partial mutual inductance due to the current in the other conductors. Looking at the image of a single-phase system, where I1 + I2 = 0...
