Uses and Application of Transformer

Uses and Application of Transformer

The most important uses and application of Transformer are:

  • It can rise or lower the level of level of Voltage or Current ( when voltage increases, current decreases and vice virsa because  P =V x I, and Power is same in an AC Circuit.
  • It can increase or decrease the value of capacitor, an inductor or resistance in an AC circuit. It can thus act as an impedance transferring device.  
  • It can be used to prevent DC from passing from one circuit to the other. 
  • it can isolate two circuits electrically.

Transformer is the main reason to transmit and distribute power in AC instead of DC, because Transformer not work on DC so there are too difficulties to transmit power in DC. in the DC Transition and distribution, the level of voltage Step up by Buck and Boost Converter but it is too costly and not suitable economically.
The main application of Transformer is to Step up ( Increase) or Step down (Decrease) the level of Voltage.
in other words, Increase or decries the level of Current, while Power must be same.
Other Uses and application of Transformer:
It step up the level of voltage at generation side before transmission and distribution.
in distribution side, for commercial or domestic use of electricity, transformer step down ( decries) the level of voltage for example form 11kV to 220 V single phase and 440 V three phase.
The Current Transformer and Potential Transformer also used power system and in the industry. Also, it is used for impedance matching.  So these were the simple uses and application of transformer.

      1. joel parde says:

        is there transformer having an input with 12volts while the output has 0v,3v,6v,9v and 12v.. the sequence of that is DC to AC ?? plss response as soon as possible.. ??

    can we convert ac into dc using transformer?

    hi. how can i cite this page? thanks :)

  11. Thanks diz rilly helped mi a lot am greatful

  12. joel parde says:

    mam/sr. can i ask something ? is there a transformer having an input 12v while the output has 0v upto 12v. that sequence is DC to AC so i mean the transformer can provide the AC output? because my source having 12VDC.

  13. Venugopal Rao Electrical Technician. says:

    Dear Sir, Kindly upload another models of single phase transformers (Step down) and its inside pictorial view, different disigns like iron core type and other core types also to know the pople about the valuable transformers how the connectivity to input and out put also. increase the subject deeply which the different transformers are using in the field of electronics (SMPS circuits) ans as well as in audio circuits.
    Thanking You Sir.

    Thank you for helping me

  16. Pradeep Kumar says:

    Transformers have lot of advantages that can work on an AC circuit to optimize the flow or current or voltage levels. Moreover they are the best alternatives to conventional circuits that are devoid of the usage of magnetic induction principle to control the voltage flow.

  17. Thanks for your kind information about transformer it is really helped me

  18. abraham mafuta says:

    thank you.this was helpfull

  19. Roger Gupta says:

    it helped me a lot in completing my project.thank’s a lot

  20. Ernest London says:

    I didn’t realize that a transformer could actually increase or decrease the value of a capacitor. That seems like it could be really important for an electrical system. I see a lot of pole mounted transformers around, and I have always been curious what they do. Thanks for the information!

  21. Umar Abdullahi says:

    Good day sir’s I was so happy and gland of what I found on this my research,what I found from u will help me a lot on my further education by god grace. I greet u, may Almighty Allah grant u and protect u in ur future.
