More questions for electrical issues

  1. Since the whole system is floating (generating system is not totally grounded), why we can use the voltage (~250Vac) that between Phase and ground (earth) to light up a bulb (load). I mean the circuit is already opened (since the generating system is floating) and current that flows through a bulb (load) is not a full one closed-loop. Example. Either positive or negative terminal of a battery and ground (natural zero potential) is not showing anything. So, why the floating generating system's phase and ground have a potential difference.


  1. In this floating generating system, the voltage between phase and ground is about 250Vac. If I touched with phase and ground directly (shorted), wherether a dangerous short circuit (something damaged) is occured or not. I mean it can cause, or not,a short like as either between Phase to Phase or Phase to Neutral



you do not. the term "floating" would indicate there is no reference to ground.

no

i recomend you stay away from generators and high voltage.

please complete the course "electronics 102 - fundamentals of AC" then ask again if necessary.

give him some Leggos and he'll leave you alone for a while.

what application?

i think you might be asking about 3 phase power distribution, however your "questions" are not clear at all.
