Jan 13, 2020 · One of the important and commonly used Transformer is Power transformer. It is very widely used for stepping up and stepping down the voltage at the electrical power generating station and distribution station (or substation) respectively. For example, consider the block diagram shown above.
- Single or three-phase transformers
- 3 MVA up to 200 MVA
- 11, 22, 33, 66, 90, 132, 220 kV
What Do Power Transformers Do? Using a process called electrical induction, a power transformer transforms the current and voltage of electricity running in it into a current and voltage that works for the specific system it’s helping to run.
Jun 19, 2023 · A power transformer is a static device that transfers electrical energy from one circuit to another without changing the frequency. It works on the principle of electromagnetic induction and can step up or step down the voltage level of an alternating current (AC) supply.
May 9, 2024 · Transformer, device that transfers electric energy from one alternating-current circuit to one or more other circuits, either increasing (stepping up) or reducing (stepping down) the voltage. Transformers are employed for widely varying purposes. Learn more about transformers in this article.
