- 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.
- 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
