t Cooling 3. In Very Simple words. Transformer is a device which: 1. Transfer Electrical power from one electrical circuit to another Electrical circuit. Work through on electric induction. When, both circuits take effect of mutual induction.
Can step up or step down the level of AC voltage or AC Current. Just imagine that there are no transformers. How many power plants do you think have to be set up in order to power up a city? It is expensive. Numerous power plant have to be set up in order to have sufficient power.
Transformers help electrical transformers pdf free download amplifying the Transformer output stepping up or down the level of voltage or current. When the number of turns of the secondary coil is greater than that of primary coil, such a transformer is known as step up transformer. Likewise when the number of turns of coil of primary coil is greater than that of secondary transformer, such a transformer is known as step down transformer. Single Phase Transformer 2.
Three Phase Transformer Below are the more types of electrical transformers pdf free download derived via different functions and operation etc. Types of Transformers w. t Cores Core Type Transformer Shell Type Transformer Berry Type Transformer Types of Transformer w. it Step up or Step down the level of AC Voltage and Current. When current in the primary coil is changed the flux linked to the secondary coil also changes.
The transformer is based on two principles: first, that an electric current can produce a electrical transformers pdf free download field electromagnetismand, second that a changing magnetic field within a coil of wire induces a voltage across the ends of the coil electromagnetic induction. Changing the current in the primary coil changes the magnetic flux that is developed. The changing magnetic flux induces a voltage in the secondary coil. A simple transformer has a soft iron or silicon steel core and windings placed on it iron core.
Both the core and the windings are insulated from each other. The winding connected to the main supply is called the primary and the winding connected to the load circuit is called the secondary. Winding coil connected to higher voltage is known as high voltage winding while the winding connected to low voltage is known as low voltage winding.
In case of a step up transformer, electrical transformers pdf free download, the primary coil winding is the low voltage winding, electrical transformers pdf free download, the number of turns of the windings of the secondary is more electrical transformers pdf free download that of the primary.
Vice versa for step down transformer. As explained earlier, EMF is induced only by variation of the magnitude of the flux. When the primary winding is connected to ac mains supply, a current flows through it, electrical transformers pdf free download.
Since the winding links with the core, current flowing through the winding will produce an alternating flux in the core. EMF is induced in the secondary coil since the alternating flux links the two windings. The frequency of the induced EMF is the same as that of the flux or the supplied voltage. Click image to enlarge Working of a Transformer By so doing variation of flux energy is transferred from the primary coil to the secondary coil by means of electromagnetic induction without the change in the frequency of the voltage supplied to the transformer.
During the process, a self induced EMF is produced in the primary coil which opposes the applied voltage. The self induced EMF is known as back EMF. Limitation of the Transformer To understand the main points, we have to discuss some basic terms related to transformer operation. So lets back to basic for a while. A transformer is an AC machine that steps up or steps down an alternating voltage or current. A transformer being an AC machine however cannot step up or down a DC voltage or DC current.
It sounds a bit weird though. Electromagnetism The interaction between magnetic field and electric current is termed electromagnetism. Current carrying conductors produces magnetic field when current passes through it. Movement of electrons in a conductor will result to electric current drifted electrons which occurs as a result of the EMF set up across the conductor. The EMF set up across the conductor can be in form of that stored in chemical energy or magnetic field.
Current carrying conductor placed in a magnetic fields will experience mechanical force while a conductor placed in a magnetic field will have its electrons drifted which will results to electric current.
Field Flux Two magnets of unlike poles will attract each other while magnets of like poles will repel each other so it is with electric charges. Every magnet is surrounded by a force field and is represented by imaginary lines emanating from the north pole of a magnet going into the south pole of the same magnet. In the course of his work he discovered that when there was change in a magnetic field in which a coil was placed, EMF was induced in the coil.
This happened only whenever he moved either the coil or the magnet he used in the experiment. EMF was induced in the coil only when there was change in the field flux if the coil is fixed, moving the magnet towards or away from the coil causes EMF to be induced. In other words, When an E. F is induced in a circuit, the current setup always opposes the motion, or change in current, electrical transformers pdf free download, which produces it.
OR An induced EMF will cause a current to flow in a close circuit in such a direction what its magnetic effect will oppose the change that produced it.
According to this law which introduced by Lens inthe direction of current can be found. when the current through a coil changes magnetic field, the voltage is created as a result of changing magnetic field, the direction of the induced voltage is such that it always opposes the electrical transformers pdf free download in current.
