Uses Of Step Up And Step Down Transformers In Daily Life

Step up transformer is used to increase the voltage and step down transformer is used to decrease the voltage level.

Uses of step up and step down transformers in daily life.

Transformer is used to get the required voltage level. The e 1 and e 2 are the voltages and t 1 and t 2 are the number of turns on the primary and secondary winding of the transformer. It step up the level of voltage at generation side before transmission and distribution. The secondary voltage is less than the primary voltage.

The number of turns on the secondary of the transformer is greater than that of the primary i e t 2 t 1 thus the voltage turn ratio of the step up transformer is 1 2. Used in our inverters 5. Used in our charges of mobiles 2. Thus it acts as an impedance transferring device.

The following images shows a simple demonstration of the use of transformers both step up and step down transformers in a typical transmission system. Step up transformers are used to increase the voltage and step down transformers are used to reduce the voltage levels. Used at distribution substation s 7. There are a wide range of transformers available in the market some of them namely toroidal isolation audio output three phase e i audio line matching smps and ui transformers.

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. Other uses and application of transformer. A step down transformer on the other hand steps down the input voltage i e. List of applications of step down transformer.

Considered a step up transformer shown in the figure below.
