Step down transformer working pdf

F in the other coil which is inductively coupled to the first coil. In its basic form, a transformer consists of two coils . The turns ratio is used to identify the step-up and step - down trans-. Every winding on the primary side will cause voltage to be induced in each winding on the secondary.

Transformers are based on the principle of “mutual-induction.

V AC to 220V AC or 220V AC to 110V AC.

At either end (both the generator and at the loads), voltage levels are reduced by transformers for safer operation and less expensive equipment.

It is designed to reduce the voltage. After studying this unit, the student will be able to. Figure 14-Schematic diagrams of step - down and step-up transformers. A transformer is an electrical apparatus designed to convert alternating current from one voltage to another. It can be designed to step up or step down voltages and works on the magnetic induction principle.

The terms step up or step down refer to the actions of the voltage. Again for an ideal transformer ,. NOTE: the transformer only works for AC voltage. Step up (or Step down ) the level of AC Voltage and Current. 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.

While operating principles of transformers remain the same, the challenges of maintaining and testing transformers have evolved along with transformer design and construction. It uses the principle of electromagnetic induction to change the voltage ( alternating difference) from one value to another whether smaller or greater. The step - down transformer converts the high voltage (HV) and low current from the primary side to the low voltage (LV) and high current value on the secondary side. When it comes to the operation voltage, the step-up transformer . Operation above the input voltage range may cause equipment damage.

Operation below the input voltage range may cause overload or automatic shutdown. A step down transformer is designed to reduce electrical voltage. Its primary voltage is greater than the secondary voltage. This article discusses different types of transformers and their applications.

DRY-TYPE DISTRIBUTION TRANSFORMERS. In this discussion, we deal with. Is it possible to use step down transformer as step transformer and vice versa if the power source is connect in reverse direction of the transformer.

Step - down pads transformer transformer.
