Impact of generator start-up on its health
In this paper, the authors state that the wear effect of a genset star-up is comparable to the wear cause by 1 to 4 minutes running at full load.
This paper dates from 1993, I am looking for a more ...

Why does a car generator employs an alternator (i.e. AC) when power supply is provided by a battery (i.e. DC)?
An alternator generates AC current, whereas batteries (as far as I know) provide/are charged with DC current. So I'm wondering, how is this apparent mismatch explained?
Do car manufacturers employ a ...

Can the power of a diesel electric generator, installed in a factory, escape into the national grid?
Say that there are two factories connected to the same 20 kV medium voltage line (see Fig. 1). Each of them has 400 V motors that consume power by turning some machines acting as mechanical loads. One ...

Is there any way to relate the induced EMF from an alternator to the DC current that is used in the field winding?
I'm trying to simulate the open circuit saturation of an alternator. Basically, by changing the amount of current that is going through the field windings (rotor), the voltage induced in the armature ...
