Let's look at this from a from a simplistic point of view.
When working with electricity, power is a combination of amperage, and voltage. Amperage drops significantly with distance, voltage does not. Because of this, a power plant generates its power as a combination of a huge voltage with very little amperage. Therefore, the power loss over long distances is minimized. Power station voltages are in the hundreds of thousands of volts.
However, these voltages are too dangerous for everyday use. Thus, they are transformed down to lower voltages such as 120 for household use, 480 for industrial, and other voltages.
During power transformation, power is not lost. Thus, if you decrease the voltage, then your amperage goes up to provide the same power.

What are the types of and uses for a transformer?
There are two types of transformers:- 1. Step-up transformer & 2. Step-down transformer. A transformer used to increase the voltage is called Step-up transformer. A transformer used to decrease the voltage is called Step-down transformer. Uses of step-up transformer:- in power supply stations, in picture tubes of TV, computer monitors, halogen lights, etc. Uses of step-down transformer:- in supply of electricity to homes, in the power supply to the low voltage devices like radio, music systems which are run by AC mains.

Why does the voltage need to be so high in a power station?
In long range,electric current can flow only when the wires are given high voltage.The voltage is about 20-30kV.eg.lightning. ---------------------------------------- Current of any voltage can flow in a wire. However, the larger the current is, the larger the resistance to flow and the greater the loss of energy during transmission. Therefore, to transfer the same amount of energy per second (power) without as much loss of energy due to resistance, current needs to be lowered by increasing the voltage since Power = Current * Voltage.
How is energy transferred from power stations to your home?
Energy is transferred from power stations to your home through the electrical grid. Power stations generate electricity, which is then transmitted at high voltage through power lines to substations. At the substations, the voltage is reduced for safe distribution to homes and businesses through power lines, eventually reaching your home through outlets.
Why the electric utility company increases the voltage of electricity for long distance transmission?
If we would like to transmit the voltage that comes staright from power stations without increasing it, we would have to use wires of size of the motorway to carry it. When we increase the voltage, current decreases which means we can use less diameter wire and we can transmit the power easly. P.zak bury
Where are transient voltage most dangerous?
when reading voltage at the meter base where power comes in the house.
How does electricity get from the power stations to the consumers?
Usually through cables. The power produced by the generator (typically 24KV) is stepped up to the transmission voltage (typically 138KV) using transformers. At various substations, transformers, again, step the transmission voltage down to distribution voltage (typically 13.2KV). There is another step down at the service pole, where a transformer converts the distribution voltage to service voltage (typically 120/240V or 480V three phase).
How many voltage is produced by a generator in all power stations?
it really depends on the station and it is referred to as distributed voltage, Our utility is 69 kv or 69,000 volts. it is stepped down to a usable voltage by transformers for distribution.
What is electricity called that comes from power station?
Power stations on a national grid generate Alternating Current (AC) This power is sometimes referred to as 'Mains' electricity or 'Network' (Netz) electricity. The output from a power station is at a very high voltage. This allows it to be sent down very long wires (Transmission Lines) without loosing voltage, due to the resistance of the wires. AC can easily be changed from high voltage to low (and back again) by a very simple transformer. The reduced voltage for use in a house, is either 230v (Europe) or 110v (USA).
What is an example of a step-up transformer?
Power stations use step-up transformers to transmit power at a high voltage instead of a high current. This reduces the power lost in the transmission lines.
Which voltages are supported by a Toshiba power supply?
The input voltage range for the Toshiba power supply is AC 100V - 240V. The output voltage is DC 19V / output current is 4.74A. This power supply comes with a power cord and packaging will state voltage recommended for the product.
Are biomass power stations just another word for nuclear power stations?
No, nothing to do with nuclear. Biomass means vegetable matter grown for burning, and comes under Renewable Energy as it can be regrown every season.
Why in a circuit using power I equals Watts divided by Volts when you increase voltage the current will reduce so why does this differ from Ohms law when you increase voltage the current increases?
When you increase voltage (V) then, to get the same total power (W), the current (I) must be decreased. This result comes from the Power Law: Power = voltage x current Ohms Law does not deal with power at all, it deals only with the relationship between voltage, resistance and current: Voltage = resistance x current
