In 1898, Stubblefield was issued U.S. patent 600,457 for an "electric battery", which was an electrolytic coil of iron and insulated copper wire that was immersed in liquid or buried in the ground. Stubblefield made the unsubstantiated claim that, combined with normal battery operation, his device also drew additional power from the earth.
A distribution system insulated from earth ground may attain a high potential due to transient voltages caused by static electricity or accidental contact with higher potential circuits. An earth ground connection of the system dissipates such potentials and limits the rise in voltage of the grounded system.
A floating ground is a reference point for electrical potential in a circuit which is galvanically isolated from actual earth ground. Most electrical circuits have a ground which is electrically connected to the Earth, hence the name "ground". The ground is said to be floating when this connection does not exist. [1]
The ground loop still exists, but the two sides of the loop are close together, so stray magnetic fields induce equal currents in both sides, which cancel out. Break in the shield Create a break in the signal cable shield conductor. [5] The break should be at the load end. This is often called ground lifting. It is the simplest solution; it ...
The "local" earth/ground electrode provides "system grounding" [13] at each building where it is installed. The "Grounded" current carrying conductor is the system "neutral". [clarification needed] Australian and New Zealand standards use a modified protective multiple earthing (PME [14]) system called multiple earthed neutral (MEN).

Earth-return telegraph is the system whereby the return path for the electric current of a telegraph circuit is provided by connection to the earth through an earth electrode. Using earth return saves a great deal of money on installation costs since it halves the amount of wire that is required, with a corresponding saving on the labour ...
