What Is Transformer

Image
The reason for transforming the voltage to a much higher level is that higher distribution voltages implies lower currents for the same power and therefore lower I 2 R losses along the networked grid of cables. These higher AC transmission voltages and currents can then be reduced to a much lower, safer and usable voltage level where it can be used to supply electrical equipment in our homes and workplaces, and all this is possible thanks to the basic  Voltage Transformer . The  Voltage Transformer  can be thought of as an electrical component rather than an electronic component. A transformer basically is very simple static (or stationary) electro-magnetic passive electrical device that works on the principle of Faraday’s law of induction by converting electrical energy from one value to another. The transformer does this by linking together two or more electrical circuits using a common oscillating magnetic circuit which is produced by the transformer itself. A

Wind energy tracking:



Wind energy can be collected through the following turbines

·         Horizontal axis wind turbine:




·         Vertical axis wind turbine:
   
                                        
When compared to vertical axis wind the horizontal axis wind turbine is commonly used type
    It is a turbine in which axis of the rotor’s rotation is parallel to the wind stream and the ground. It is built with a propeller type rotor on a horizontal main shaft. It may be two (or) three or multi blades. The rotor converts linear motion of the wind into rotational energy that is used to drive a generator.
      The basic principle is that flow of air is parallel to the rotation axis of the turbine blades. The wind passes over both surfaces of the blade creating a low pressure area above the air foil. The pressure differential between the top and bottom surface results in aerodynamic lift. The blades of the turbine are constrained to move in a plane with the hub as it’s centre, the lift force causes rotation about the hub.

Generating electricity from wind mills:

    Wind power converts the kinetic energy in the wind to generate electricity or mechanical power. This is done by using a large wind turbine usually consisting of propellers; the turbine can be connected to a generator to generate electricity, or the wind used as mechanical power to perform tasks such as pumping water or grinding grain. As the wind passes the turbine blades it spins the shaft and it is connected to generator which converts the mechanical energy into the electrical energy.

Renewable Resources

Renewable Resources: Renewable resources   are resources that are replenished by the environment over relatively short periods of time. This type of resource is much more desirable to use because often a resource renews so fast that it will have regenerated by the time you've used it up. Think of this like the ice cube maker in your refrigerator. As you take some ice out, more ice gets made. If you take a lot of ice out, it takes a little more time to refill the bin but not a very long time at all. Even if you completely emptied the entire ice cube bin, it would probably only take a few hours to 'renew' and refill that ice bin for you. Renewable resources in the natural environment work the same way. Solar energy is one such resource because the sun shines all the time. Imagine trying to harness all of the sun's energy before it ran out! Wind energy is another renewable resource. You can't stop the wind from blowing any more than you can stop the sun fro

Wave Power

Image
Wave Power: Wave energy is produced when electricity generators are placed on the surface of the ocean. The energy provided is most often used in desalination plants, power plants and water pumps. Energy output is determined by wave height, wave speed, wavelength, and water density. To date there are only a handful of experimental wave generator plants in operation around the world. The articles on this page explore the world of wave energy and its possible applications.
