But in the problems they did not mention what kind of power so how can i tell they are apparent, real or reactive powers if I see any similar problem like this?Apparent power (S) is determined by: S=VI*.
You only start caring about the power factor if you are concerned about real and reactive components such as what happens when you start examining loads with non-like power factors.
Since all they are looking for is the magnitude of the current, the angle doesn't matter.
They did mention the type of power. It was KVA, therefore ILine = S/(sqrt3)(ELine) for 3 phase. No need to use power factor. Power factor was just a distraction.But in the problems they did not mention what kind of power so how can i tell they are apparent, real or reactive powers if I see any similar problem like this?Apparent power (S) is determined by: S=VI*.

Anyway, thanks for your time.
I understand how this was calculated, I'm just confused as to if this is the standard way they state the specifications of a generator. How do I know that the 2.4 kV stated is phase voltage and not line voltage?Problem 110 is a single phase problem. Even though they are connecting to a three-phase system, they are only connecting a single phase load and the voltage between the phases is given.
Problem 121 is a three phase problem.
I've never seen a 3-phase generator rated in anything other than VLine. If the information is given as a phase voltage, it should explicitly state that it as such.I understand how this was calculated, I'm just confused as to if this is the standard way they state the specifications of a generator.
