Transfer Electrical power from one electrical circuit to another Electrical circuit. Work through on electric induction. When, both circuits take effect of mutual induction.

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 by 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 transformer derived via different functions and operation etc. Types of Transformers w. 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 magnetic field electromagnetism , and, 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. This Book provides an clear examples on each and every topics covered in the contents of the book to provide an every user those who are read to develop their knowledge. The text presents the topic in a clear, simple, practical, logical and cogent fashion that provides the students with insights into theory as well as applications to practical problems.

Electric Power Transformer Engineering 2nd Edition written to meet exhaustively the requirements of various syllabus in the subject of the courses in B. Sc Engineering of various Indian Universities. Harlow Free? You all must have this kind of questions in your mind. Below article will solve this puzzle of yours. Just take a look. The reason is the electronic devices divert your attention and also cause strains while reading eBooks.

For its second edition, this popular progeny rejoins the handbook as one in a set of five carefully focused volumes. In addition to updates in nearly every chapter, this highly regarded reference brings to the Handbook its original contributions, discussing phase-shifting, rectifier, and constant-voltage transformers as well as power transformer protection and transient-voltage response.

It also includes two new sections in the chapter on reactors, covering installation considerations for dry-type air-core reactors as well as line traps and power line carrier communication-, data-, and protective-relaying systems.
