In electricity, what does floating ground mean?
149208
I believe that a "floating ground" is used on large seagoing ships (pun intended!).  Seriously, the floating ground avoids using the ship's structure including the hull from carrying large electrical currents that may promote corrosion.  Often sacrificial zinc plates are also placed on the hull to avoid galvanic corrosion, especially because the properrers are bronze and the hull is steel.  With a floating ground system, electric supply cables must also include sufficient ground wires to permit current to flow between the ship's generators and all loads and back to the generators.  The frames of machines and electronic devices must also use the floating ground system to avoid shocks to the crew.

1.A floating structure, such as a flatbottom boat, that is used to support a bridge. \n2.A floating structure serving as a dock. \n3.A float on a seaplane.

Grounded means you can't do something. I get grounded from going to dances or grounded to the house for a week or to my room for a day. When I was younger if I was really bad I might get put to bed early. That is sort of grounded to your bed. Time out chair is sorta like grounding. Usually if I was bad enough to get grounded to my bed, I got spanked too. Grounding sucks!

Ice floating is because of water's expansion upon freezing. It lowers the density below that of liquid water, meaning it floats.

Static electricity builds up along the surface of the balloon when friction is applied, causing an electrical charge. This is the same phenomenon that occurs when you walk across a carpeted floor then touch a door handle, or another person and get shocked.

I work on diesel - electric locomotives .The power system and components ( high voltage and amperage ), such as the traction motors,are protected by a 'ground relay ' that 'trips' and cuts power when a ground fault exists.\n In our terms a 'ground fault' means that the negative or positive cables or components are grounded, meaning the insulation is bad and the circuit touches the body at that bad spot, referred to as ground. (ground is referred to as the general mass of earth ) and the locomotive is basically on earth through the wheels on the rails.\nWe use a 1000 volt meggar meter , one lead coupled to the positive or negative power circuit, and the other lead coupled to ground, and then we send 1000 volts into the system and it indicates/reflects to what extent the circuit is grounded and by isolating different parts of the circuit we can detect exactly where the ground fault is situated by reading the power schematic .(electrical drawing or plan )Hope it explains enough.

Because they use a lightning rod to conduct the current directly to the ground.

It is supposed to ground your energies. Bubbling might signify energy trying escape. Maybe it is blocked/closed?

It means, you are using their electricity.  The faster it moves the more you are consuming.  Try this link:

Your concept of the linesman is correct, however, being immersed in a body of water is dangerous.  Lightning carries a far greater potential than that of what the linesman faces.  True, there is no conduction of current to ground, but the copter and the line must be equalized before contact can be made.  This is because of the state of "STATIC ELECTRICITY".  Energy that is "Static" is not moving.  Nevertheless, when it comes in contact with another object, one who's energy level is at a different potential, the energy no longer remains static.  The sudden rush of current will be felt.  That's why when you cross the rug and grab the door knob you get a shock.  You have a significantly higher potential than the door knob and when you touch it there is a rush of energy trying to equalize the differences.\n\nBeing in a pool at essentially zero volts and a crack of lightning hits close by, the ground and the water in the pool will charge up before dissipating the lightning strike, possibly leaving you dead.  Wouldn't that ruin your day?\n\nDuring lightning storms stay out of the pool or the tub, do not be running the sink and stay off the phone (cordless phones do not apply in this case as there is no direct wiring to the outside world).  There have been documented cases where persons on the phone have been struck in the head by lightning, again it's due to that equalization of energy levels thing.\n\nHey, even if everyone is wrong, wanna risk your life?  You could die in a tub if someone dropped something electrical in the water.  True, your assumption is that water conducts better than the human body, but that is a wrong assumption.  Pure water is an insulator.  It's the impurity in water that makes it conduct.  Our bodies are actually much better conductors of electricity.  Don't believe me?  Ask someone like an electric shop teacher.\n\nI hesitate to give you a test to try because of the danger of electrocution, but if I were at your house I could demonstrate in a matter of seconds that what I am saying is true.  But for the sake of not causing someone to try a potentially dangerous experiment I'll not be specific.\n\nHowever, if you must know, e-mail me and we can chat.  When I am confident of your ability to conduct the test safely then I will tell you how to do this.

Actually eclipse is wrong on the static dischargers, too.  All they do is slowly get rid of any excess charge on the plane relative to the surrounding air.\n\nThe answer to the ? is that planes AREN'T grounded electrically.  All the electrical and electronic stuff in them is grounded to the metallic structure of the plane, snd this is the return path for all current using devices.  Planes made of certain non-conductive composites use separate grounding wires and busses to do the job.

You are electrically charged...it's like a mini-lighting storm... the touching of electrons causes a little clash.\nIt's an energy thing.\n\nHowstuffworks.com has a science section. It can explain electricity.

First you have to know "Static electricity" is not electricity which is static. \n\n"Static electricity" is all about charge-imbalance, and it has nothing to do with charges at rest. "Static electricity" was misnamed.\n\nWhen we scuff our shoes upon a rug on a dry winter day, our bodies typically charge up to a potential of several thousand volts with respect to the ground. In physics this is a well-known fact, and is easily verified by meter measurements. Touch a grounded object, and a spark will leap between the object and your fingertip. This kind of electric spark can only exist when a high voltage is present. The tiniest spark requires about 500 volts. Big, nasty, painful sparks require lots more voltage, up to several thousand volts. But even when no sparks are jumping, there is still a high voltage between your charged body and the ground, and your charged body is surrounded with an invisible electric field.\n\nThere are many way you can eliminate it, Refer to this web you can will able to know.\nhttp://www.school-for-champions.com/science/staticcont.htm

.......because electricity looks for the closest path to the earth........and you standing on the ground, combined with the fact that humans conduct electricity - means that you're its route to the earth!

electric charges go from ground to sky. The lightning is the effect (also the thunder) of such traveling charges.
