Why is a transformer's split phase secondary neutral grounded?
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.
Does the Voltage measurement of earth ground vary with geographic location?
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.
How are ground wires a safety measure against electric shock?
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.
What is the voltage to ground of 13800 volts line to line?
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.
What is the difference between a radar altimeter and a barometric altimeter?
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.
Why is earth a rock?
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.
Give names for the molten material in the Earth and molten material outside the Earth?
Molten material below ground is called magma, and molten material above ground is called lava.
What is the earth wire for in a plug?
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.

How do you calculate the force of a high heel?
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.
What was George Washingtons statement a freeman contending for liberty on his own ground is superior to any slavish mercenary on earth about?
He did give up his slaves if that's what you mean.
What differences does earth and mercury have between them?
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!
What did gunther and tinka give cece and rocky for preforming at clouse's birthday party?
Actually, they refused to pay them or give them anything.
Why does earth give life?
yes earth can give life because it has atmosphere
