Uses Of Step Up And Step Down Transformers In Daily Life

Transformer is used to get the required voltage level.

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

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. Step up transformers are used to increase the voltage and step down transformers are used to reduce the voltage levels. Step up transformer is used to increase the voltage and step down transformer is used to decrease the voltage level. Other uses and application of transformer.

Transformer can increase or decrease the value of capacitor an inductor or resistance in an ac circuit. Considered a step up transformer shown in the figure below. 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. It step up the level of voltage at generation side before transmission and distribution.

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 at distribution substation s 7. The following images shows a simple demonstration of the use of transformers both step up and step down transformers in a typical transmission system. Thus it acts as an impedance transferring device.

A step down transformer on the other hand steps down the input voltage i e. Used in our inverters 5. Almost in all elect. Used as welding transformers 6.

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.
