Transformers transform low vvoltages to hivh and vice versa. This is important in transmitting electrical power form the high voltage power plant to the low voltage home voltage. Using high voltage transmission reduces transmission power losses, I2R.

How much does transformer oil weigh?
7.6 pounds/gallon
What is density of transformer?
density of transformer is 1.98
Step down transformer of a specs of 110 primary to 24 v 12va CAn you used a 110v primary to 24v 20 va What is the difference between them?
Yes. The Va numbers indicate the rating of the transformer (12VA indicates that you can draw upto 12/24 = 1/2 Amps at 24 volts and 20VA indicates that you can draw about 20/24 = 0.83 Amps). Usually 20va transformer will cost more than the 12va transformer. So, unless a higher power output is required, it is adequate to use the lower rating transformer. However, you cannot go the other way - if you use a 12va transformer in-lieu of the 20va one, if the application needs more power, then you have a reliability problem. The transformer will have more loss, heat-up and then eventually burn out.
How is electrical energy transferred in a transformer?
It is important to note that that transformer input and output are isolated from one another, in the sense that an electrical charge cannot move from input to output. The energy is transferred via the magnetic field. The alternating current in the input causes a magnetic field; this magnetic field causes an alternating current in the output.
Why transformer not rotating?
transformer is not rotating bcoz for rotating rotating magnetic field is required which is produced only when the current is passed through the windings which are displaced physically by 120degrees and phase difference of 120 degrees where as in transformer there is no phsical displacement of 120degrees hence transformer cannot rotate.
What were the most important trends in coil and transformer production?
The most important trends in coil and transformer production were continued miniaturization and weight reduction, as well as surface mounting
What are the advantages of double wound transformer over a auto transformer?
The difference between a double wound step up transformer and an auto transformer is the double wound on the step up transformer and the single wound on the auto transformer.
How is current controlled in welding transformer?
in welding machine, the transformer used is basically a current transforrmer. so by changing the tap of secondary side of transformer, we can increase or decrease the current in the transformer.
How do you load a transformer?
Anything that draws energy from a supply is a load. So you 'load' a transformer by attaching a lamp, a motor, etc., to the transformer's secondary windings.
Why the polarity of transformer is important?
a polarity test is a test which use to check the polarity of tranformer.the rision of this test to running the two or more transformer in parallel.like bettry situation or to fin the terminals
What type of transformer is used in a resistance furnace?
A resistance furnace runs on electricity so it will be some type of electrical transformer.
What type of transformer do you need to run your out door low voltage garden lights max 200 watt And most important where can one purchase one Thank you?
You will need a standard AC transformer. You can purchase the transformer at most Home Depot's.
How you using ref relay in transformer?
an REF relay (restricted earth fault) is used to provide ground fault protection for a transformer. Its' operation is limited by CTs starred towards the transformer (usually on the transformer bushings or in breakers used to isolate the transformer), so it will only operate for transformer related faults. Because of this, it can be set to operate very quickly.
What are the major faults of a step down transformer?
A step-down transformer does just what it's designed to do, so there are no 'major' faults associated with it.
What can you do as preventative maintenance for a power pole transformer so that the mineral oil does not boil?
Lower the rating of the primary fuse feeding the transformer.
Can a distribution transformer be used as a potential transformer?
I'm not quite sure what you mean by a "potential transformer", but I look at it this way: The transformer isn't aware of the purpose to which you're putting it, so no matter what you call the function, the transformer continues to perform it ... transforming voltages and impedances in proportion to the turns ratio, and currents in proportion to its inverse.
Why are transformer more efficient that rotating electric machines?
Because the electrical parts of a transformer do not move / rotate.
