How do Submarines, Planes, Ships, Spaceships, etc. Ground their electrical systems to prevent their entire surface from becoming an electrical hazard?
In: Engineering
It can only be an electrical hazard if there is a nearby surface at a different voltage. By connecting the device to this surface, their voltages match and thus the device is ‘grounded’.
If not, then there is no hazard.
That said, there can be issues with grounding in space. Ships, subs, and to a lesser degree planes are inherently grounded, having such extensive contact with the ocean, but satellites and the like do not. They could, in theory, build up charge.
That said, even in space, you’ve got a lot of charged particles whipping around that you could equalize your charge with.
