MAGLEV TRAINS



ABSTRACT:

The concept of magnetically levitated or maglev trains is of very much interesting.
The conventional trains with wheels and guide rails turn to be uneconomical beyond 200 km/hr because at this high speed, air resistance and hence the drag force increases. Therefore, they are very much expensive and require intensive maintenance. Maglev trains avoid these disadvantages and prove highly beneficial.

It is based on the three principles viz. electrod ....etc

APPLICATION OF SUPERCONDUCTIVITY IN ELECTRIC POWER SYSTEM
1.0. INTRODUCTION
With the discovery of High Temperature Superconducting materials the possibilities of applications of the Superconducting technology in power system have become very bright.
Superconductivity is characterized by an important feature of zero resistivity, which means that superconductor is perfectly electrical conductor. The other critical parameters are: critical Temperature, Critical Magnetic field and critical current Den ....etc

Maglev Trains


1. INTRODUCTION
1.1 History
First generation Maglev systems have been developed in Japan and Germany.
Hermann Kemper began research on Maglev system in Germany and conducted successfully tests in the 1930’s (receiving a patent in 1934).
In the late 1960’s the German government began a study of traffic and modes which led to the development of very high speed maglev system by the German ministry of research and technology. The development included short stator, EDS and EMS technology and sy ....etc

1. Introduction
Superconductivity is a phenomenon occurring in certain materials generally at very low temperatures, characterized by exactly zero electrical resistance and the exclusion of the interior magnetic field (the Meissner effect). It was discovered by Heike Kamerlingh Onnes in 1911. Applying the principle of Superconductivity in microwave and millimeter-wave (mm-wave) regions, components with superior performance can be fabricated. Major problem during the earlier days was the that the cryogenic burden has been perceived as t ....etc

SUPERCONDUCTIVITY is the ability of certain materials to conduct electric current with no resistance and extremely low losses. This ability to carry large amounts of currents can be applied to electric power devices such as motors and generators and to electricity transmission in power lines.

For example, superconductors can carry as much as 100 times the electricity ordinary copper or aluminium wires of same size.Scientists had been intrigued with the concept of superconductivity since its discovery in the early 1900?s, but the extreme low ....etc
