Difference Between Step-up and Step-down Transformer - Circuit GlobeThe main difference between step-up and step-down transformer is that, step-up transformer increases the voltage whereas a step-down transformer decreases the voltage. The secondary voltage of step-up transformer is more than that of its primary voltage whereas the secondary voltage of step-down transformer is less than its primary voltage. In fact, these two terms, i. From construction and design point of view, there is no difference between step-up and step-down transformer. A given transformer can be used as step-up or step-down transformer. If the HV High Voltage winding is connected to supply main and LV low voltage winding to load, the transformer works as Step-down transformer. This is because, the transformer is delivering the power at a decreased voltage at secondary terminal.

If the HV High Voltage winding is connected to supply main and LV low voltage andd to load, the transformer works as Step-down transformer.The strength of the voltage at the secondary winding is dependent on the number of windings through which the flux gets passed through. The alternating current will result in an alternating magnetic flux, which passes eown the iron magnetic core and completes its path. Both transformer types have the same design and construction. In fa.

A transformer is static electrical equipment which transforms electrical energy from primary side windings to the magnetic energy in transformer magnetic core and again to the electrical energy on the secondary transformer side. The operating frequency and nominal power are approximately equal on primary and secondary transformer side because the transformer is a very efficient piece of equipment — while the voltage and current values are usually different. Essentially, that is the main task of the transformer, converting high voltage HV and low current from the primary side to the low voltage LV and high current on the secondary side and vice versa.

A transformer is a static device which transfers a. For economical reasons, electric power is required to be transmitted at high voltage whereas it has to be utilized at low voltage from a safety point of view. This increase in voltage for transmission and decrease in voltage for utilization can only be achieved by using a step-up and step-down transformer. The major difference between step-up and step-down transformer is, step-up transformer raises the output voltage, whereas step-down transformer reduces the output voltage. Some other differences are explained below, in the form of a comparison chart, considering the factors: voltage, winding, the number of turns, thickness of conductor and application.
Discover everything Scribd has to offer, giant power step-up transformer is used as generating step-up transformer for stepping up the generated power to a higher voltage level for efficient transmission purposes. I was also told that whatt cannot use an ordinary step down transformer as a step up Tx, but why. As we told already, including books and audiobooks from major publishers. S M Akash.
January 24, giant power step-up transformer is used as generating step-up transformer for stepping up the generated power to a higher voltage level for efficient transmission purposes, by Electrical4U. As we pd already. It depends upon the ways in which it is connected in the circuit. Don't have an AAC account.Take a thick iron rode and cover it with thick paper and wind a turns of copper wire on it. Rate of change of magnetic flux linked with each turn of secondary coil is less than rate of change in magnetic flux linked with donw turn of primary coil. Also read Introduction to Transformers. The voltage with decreased level is then made ready for consumer use!
Log in to comment. One can distinguish a transformer as step-up or step-down only after having knowledge of their application. Arpit Tyagi. Since the secondary voltage is decreasing from 11 kV to V, it is called a step-down transformer.
