Step-up Transformers used in the transmission of electrical energy increase the voltage going over Transmission Lines (over 100,000 Volts). For a given amount of POWER to be Transmitted, the higher the Voltage, the LOWER the CURRENT. This reduces the amount of Power LOST to the Resistance of the Transmission Lines.

Power Lost is calculated by the Formula:

POWER Lost = I2 x R, where I=Current and R=Resistance

So, the lower the Current (I), the lower the transmission line losses.

At the end of the Transmission Path the Voltage is "Stepped Down" to a value usable for the Customer, usually (220 volts for Residential use in the USA).

What is the name given to the large transformers used in transmission systems to step up and step down?

step up transformer


Which type of electrical power-related tranformer steps up the voltage to several hundred thousand volts in order to reduce energy losses?

Step-up transformers of the type you describe are three-phase transformers which, in the transmission system, are classified as 'power transformers'.


Differentiate step-up transformers from step-down transformers?

Step up transformers increase the voltage, while step down transformers reduce it. Higher voltages are better for electricity transmission/distribution, because, for any given load, the higher the voltage, the lower the resulting current. This means the supply conductors can have a lower cross-sectional area and the resulting saving in copper makes the installation cheaper. A lower load current also means lower line (energy) losses.


How can you convert 1000000 volts to several hundred 9 volt power sources?

On the whole AC electrical conversions are done with transformers. In your question both step up and step down transformers will be utilized. Step up transformers will be utilized to get the generated voltage up to transmission voltage. At the voltage transmission destination the voltage will use step down transformers to decrease the voltage to the consumers load requirement. Or you could connect 111111 resistors in series and take the voltage off each one of them .. but ull have to put in consideration the load resistance ..


Which part of the process of distributing electricity changes the voltage of the current?

The transformers step-up and down voltage for transmission and use.

How are step-up and step-down transformers used in the transmission of electric current from the electric company to homes?

(This is what my teacher said, I wrote this down in my notes) The answer is, Step-up transformers are used to increase the voltage of an electric current before it is sent out over transmission lines from the electric company. Step-down transformers are used to reduce the voltage of current from high-voltage transmission lines before it enters homes and businesses. Some devices, such as televisions, contain step-up transformers that increase the voltage once again.

How are step-up transformers used in the transmission of electrical energy?

Step-up transformers are used in the transmission of electrical energy to increase the voltage of the electricity before it is sent over long distances through power lines. This higher voltage reduces energy loss during transmission, making the process more efficient and cost-effective.


What is the name of a step-up which increases the voltage of electric energy that is generated at a power?

The name of the step-up device which increases the voltage of electric energy generated at a power plant is called a transformer. Transformers are used in electricity distribution systems to increase the voltage for efficient long-distance transmission before stepping it down again for use in homes and businesses.


How is energy lost from power stations to homes?

Energy is lost during the generation, transmission, and distribution of electricity from power stations to homes in the form of heat due to resistance in power lines and transformers. This energy loss is known as transmission and distribution loss, and it occurs as electricity travels long distances over power lines. Transformers are also used to step up or step down voltage, which can result in additional energy loss.


Distribution transformer vs power transformer?

Power transformers are step-up or step-down transformers used in the electricity transmission system, whereas distribution transformers are step-down transformers used in the electricity distribution system.

What we use of automatic Electric transformer use in power transmission?

"Electric" transformers are used in the electric power system for many things. I wonder if you mean "auto" transformer. Transformers are used to step up/down voltage and currents, to provide a ground reference, to inject signals onto power lines, to sample high voltages and currents, etc.


What is transmission of power?

it is basically the transportation of electrical power from the power generation plant (eskom) via step up voltage transformers to the substation (step down transformers. to the distribution of the consumers.


Why are transformers used for transmission of electricity into your home?

The voltage provided by power company are higher what your home uses so transformers step down the voltage for your house. Higher voltages in your home would cause a potential safety hazard. The higher voltages on transmission lines are used to cope with voltage drops over long distances.
