1. USE GROUNDING TRANSFORMER OR ZIGZAG TRANSFORMER 2. USE SOIL CONDITIONING AGENTS - MARCONITE CONDUCTIVE AGGREGATE AND BENTONITE MOISTURE RETAINING CLAY ON EARTH ELECTRODE BACKFILL.
The secondary of a transformer is isolated (floating) relative to the primary, so there is no absolute reference relative to earth ground on the secondary side. By connecting the neutral to ground (earth ground that is) this creates an absolute reference. This also creates a leakage path to earth ground, now that the secondary voltage is referenced to earth ground, but that is more desirable than not because otherwise something else in the system might improperly provide that reference.
Yes it very much depends upon what type of soils are in the region. In some very dry locations the ground wire is strung along with the rest of the pole wires from pole to pole. In very gravelly soil conditions there is no grounding medium no matter how deep the ground rods are placed. Other places that give trouble is solid rock installations.
If the live wire should touch the casing of an appliance, the casing would become live and give electric shocks. The ground wire prevents this because it provides a low resistance route to earth and any current flows away safely. Because of the low resistance, a large current flows and blows the fuse, thus disconnecting the appliance. One safety feature is that the ground wires connect the outer cases of all items of electrical equipment together, so that (for example) it is not possible to get an electric shock by touching the cooker and the fridge at the same time. This type of grounding is also used in aircraft even though there is no connection to the ground. The other feature is that the ground wires are grounded to an earth rod in the ground, to avoid a buildup of static electric charge. They are also connected to water and gas supply pipes.
On a three phase system with a line to line voltage of 13800, a wye connection will give you a voltage of, 13800/1.73 = 7977 volts to ground.
Radar altimeter gets altitude information by bouncing a radio wave off the surface of the Earth and determines the aircrafts altitude by measuring the length of time it takes for the signal to return. Barometric altimeters get altitude information by measuring the barometric air pressure outside the aircraft. Barometric pressure decreases as altitude increases. Radar altimeters will give altitude above ground level while barometric altimeters give altitude above sea level.
Earth is known as a rocky planet because it is primarily composed of silicate minerals and metals. Its solid surface is made up of a combination of rocks and minerals, which give it its characteristic features. Several geological processes over millions of years have shaped Earth into the rocky planet we see today.
Molten material below ground is called magma, and molten material above ground is called lava.
In the USA we call it the ground. If there is a cross in the wires from hot to common the ground or earth wire will give the electricity an easier path to the ground instead of going through a live person. The earth is attached in the main box to a copper rod hammered into the ground. This makes it easier for electricity to get to the ground.

go away I suggest that is what you do if you cannot give a sensible answer. A barrow in this instance is an ancient earth burial ground

The force of a high heel can be calculated using the formula Force = Pressure x Area. To calculate the pressure, divide the weight of the person wearing the high heel by the area of the heel that contacts the ground. This will give you the force exerted by the high heel on the ground.
He did give up his slaves if that's what you mean.
They have an iron core between them and they have a rocky surface. they both turn anti-clockwise. They first didn't have any life on either planet.I hope that helps, please give me a vote for that!
Actually, they refused to pay them or give them anything.
yes earth can give life because it has atmosphere
