Gate 2015

GATE 2015

  Graduate Aptitude Test in Engineering (GATE) is an all India examination that primarily tests a comprehensive understanding of various undergraduate subjects in engineering and technology is an all India examination that primarily tests the comprehensive understanding of various undergraduate subjects in Engineering and Technology. GATE is conducted jointly by the Indian Institute of Science and seven IITs (IIT Bombay, IIT Delhi, IIT Guwahati, IIT Kanpur, IIT Kharagpur, IIT Madras and IIT Roorkee) on behalf of the National Coordination Board-GATE, Department of Higher Education, Ministry of Human Resource Development (MHRD), Government of India

The GATE score of a candidate reflects a relative performance level in a particular paper in the exam across several years
The score is used for admissions to post-graduate engineering programmes (i.e. M.E., M.Tech, direct Ph.D) in Indian higher education institutes with financial assistance provided by MHRD and other Govt agencies

Admission to post graduate programmes with MHRD and some other government scholarship/assistantship at engineering colleges/institutes in the country are open to those who qualify through GATE. GATE qualified candidates with Bachelor degree in Engineering / Technology/ Architecture / Pharmacy or Master degree in any branch of Science / Mathematics / Statistics / Computer Applications are eligible for Master / Doctoral programmes in Engineering/ Technology / Architecture / Pharmacy as well as for Doctoral programmes in relevant branches of Science. To avail the financial assistance (scholarship), the candidate must additionally secure admission to such a postgraduate programme, as per the prevailing procedure of the admitting institution. GATE qualification, however, is not required for candidates with Master degree in Engineering / Technology / Architecture / Pharmacy who may be seeking scholarship/assistantship for relevant doctoral programmes.

EE(Electrical Engineering)

EE stands for Electrical Engineering and this will always get differ from Electronics Engineering.And this Electronics Engineering paper will include different portions for preparing. so kindly check your syllabus for your B.E program on the gate website GATE EE 2015 SYLABUS

Transformers

Transformers:

A transformer is a static machine used for transforming power from one circuit to another without changing frequency. This is a very basic definition of transformer.

History of Transformer:

The history of transformer was commenced in the year 1880. In the year 1950, 400KV electrical power transformer was introduced in high voltage electrical power system. In the early 1970s, unit rating as large as 1100MVA was produced and 800KV and even higher KV class transformers were manufactured in year of 1980.

Power Transformers:

Generation of electrical power in low voltage level is very much cost effective. Hence electrical power is generated in low voltage level. Theoretically, this low voltage level power can be transmitted to the receiving end. But if the voltage level of a power is increased, the electric current of the power is reduced which causes reduction in ohmic or I2R losses in the system, reduction in cross sectional area of the conductor i.e. reduction in capital cost of the system and it also improves the voltage regulation of the system. Because of these, low level power must be stepped up for efficient electrical power transmission. This is done by step up transformer at the sending side of the power system network. As this high voltage power may not be distributed to the consumers directly, this must be stepped down to the desired level at the receiving end with the help of step down transformer. These are the uses of electrical power transformer in the electrical power system.

.

Types of Transformers:

Transformers can be categorized in different ways, depending upon their purpose, use, construction etc. The types of transformer are as follows,

1. Step Up Transformer & Step Down Transformer - Generally used for stepping up and down the voltage level of power in transmission and distribution power network.
2. Three Phase Transformer & Single Phase Transformer - Former is generally used in three phase power system as it is cost effective than later but when size matters, it is preferable to use bank of three single phase transformer as it is easier to transport three single phase unit separately than one single three phase unit.
3. Two Winding Transformer & Auto Transformer - Former is generally used where ratio between high voltage and low voltage is greater than 2. It is cost effective to use later where the ratio between high voltage and low voltage is less than 2.
4. Outdoor Transformer & Indoor Transformer - Transformers that are designed for installing at outdoor are outdoor transformers and transformers designed for installing at indoor are indoor transformers.
