Uses Of Step Up And Step Down Transformers In Daily Life

Used in our inverters 5.
Uses of step up and step down transformers in daily life. Used at distribution substation s 7. Used in our charges of mobiles 2. Step up transformers are used to increase the voltage and step down transformers are used to reduce the voltage levels. 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.
Almost in all elect. It step up the level of voltage at generation side before transmission and distribution. Used as welding transformers 6. A step down transformer on the other hand steps down the input voltage i e.
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. List of applications of step down transformer. The secondary voltage is less than the primary voltage. 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 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 transformer is used to increase the voltage and step down transformer is used to decrease the voltage level. Thus it acts as an impedance transferring device. Considered a step up transformer shown in the figure below.
Transformer is used to get the required voltage level.
