Transformer Introduction The transformer is one of the simplest of electrical devices. Its basic design‚ materials‚ and principles have changed little over the last one hundred years‚ yet transformer designs and materials continue to be improved. Transformers are essential in high voltage power transmission providing an economical means of transmitting power over large distances. The simplicity‚ reliability‚ and economy of conversion of voltages by transformers was the principal factor in the

Experiment No: 2 Open circuit and short circuit tests on single phase transformer 1 Aim • To understand the basic working principle of a transformer. • To obtain the equivalent circuit parameters from OC and SC tests‚ and to estimate efficiency & regulation at various loads. 2 Theory The physical basis of the transformer is mutual induction between two circuits linked by a common magnetic field. Transformer is required to pass electrical energy from one circuit to another‚ via the medium

Ques-1: What is a transformer and how does it work? Ans: 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. A transformer has no moving parts and is a completely static solid state device‚ which insures‚ under normal operating conditions‚ a long and trouble-free life. Construction of transformer is very simple‚ two or more coils of insulated

A transformer is a static machine used for transforming power from one circuit to another without changing frequency. This is very basic definition of transformer. History of Transformer The History of transformer commenced in the year of 1880. In the year of 1950 400KV electrical power transformer first introduced in high voltage electrical power system. In the early 1970s unit rating as large as 1100MVA were produced and 800KV and even higher KV class transformers were manufactured in year

History of Electric Transformer INTRODUCTION: Transformer is a device that transfers electric energy from one circuit to another‚ usually with a change in voltage. Transformers work only with a varying electric current‚ such as alternating current (AC). Transformers are important in the distribution of electric power. They raise the voltage of the electricity generated at a power plant to the high levels needed to transmit the electricity efficiently. Other transformers reduce the voltage

what we’ve seen or heard and use our judgment to determine who is good or evil and who we wish to see conquer the other. The feature film Transformers‚ directed by Michael Bay and executive producer Steven Spielberg in 2007 is a science fiction‚ action film that copes with the aspects of good and evil through the Autobots and humans who fight for survival and power against the devious Decepticons . The film presents the Autobots to me as respectful and virtuous characters that believe in harmony and

The Transformers Transformers is a live action movie released by DreamWorks in 2007. The story follows the Transformers’ arrival on modern-day Earth and their interactions with the human race‚ as they search for the life-giving AllSpark and continue their ages-old civil war. The movie is fiction but also distinct in its own right. My favorite "Transformers" character is Bumblebee who is a robot that transforms into Sam’s car. I like him because he is a loyal Transformer and transforms into a Camaro

CHAPTER 1 INTRODUCTION Power transformers are very important in the electrical power sector; they are among the expensive assets of power generation and distribution systems. . According to Piush Verma [16]‚ transformers are static electromagnetic devices consisting of two or more windings which are linked with a common magnetic field used for the distribution of electrical power from one voltage level to another. Some of the main parts of the transformer are; the windings‚ tank and insulation
