Hi friends, in this article, I am going to discuss types of concentrating solar collectors and hope you will find it useful. Solar power is a conversion of sunlight into electricity. The amount of solar energy reaching the earth’s surface is huge – almost 6000 times more than the power consumed by humans throughout the world. […]
In motor control circuits, a diode known as the freewheeling diode is connected across motor terminals to allow for dissipation of energy stored in motor inductance and to provide for continuity of motor current when the SCRs are blocked. It also provides protection against transient over voltages. Freewheeling Diode in Controlled Rectifier Energy Stored in
Hi friends, In this article, I am going to discuss components of HVDC system, working, types, advantages and disadvantages of the HVDC transmission system. I hope you will find it useful and exciting. Transmission and distribution of electric power are done using alternating current, mainly due to economic reasons. However, due to the development of
Wind energy is an indirect form of solar energy since wind is produced chiefly by the uneven heating of the earth’s crust by the sun. The kinetic energy of the wind can be utilized to produce with the help of wind turbine. Wind Power Plant Working Principle As the free wind stream interacts with turbine
As per present terminology, voltages less than 300 kV are termed as High Voltages. The voltages in the range of 300 kV to 765 kV are known as Extra High Voltages (EHV). The voltages which are 765 kV are termed as Ultra High Voltage (UHV). In India, transmission voltage ranges from 66 kV to 400
Normally, no current flows through insulators or dielectric materials. However, when the voltage applied to such materials exceeds a certain value, then it breaks down and a heavy electric current (much larger than the usual leakage current) flows through it. If the insulator is a solid medium, it gets punctured or destroyed. Dielectric Strength Definition

Construction, Classification & Advantages of Cables The transmission and distribution of electrical power can be done with the help of overhead transmission lines or by underground cables. It has been mentioned that in thickly populated areas like towns and cities, the use of overhead lines is not practicable. In such cases, electrical energy is transmitted

Construction of 3 core underground cable is shown in Figure. The different parts of it are as under: Core or Conductors: A three core cable has three conductors as shown in Figure. These conductors are made of copper or aluminum and usually stranded to make the cable flexible. Insulation: Each core or conductor is covered by a
Hi friends, in this article, I am discussing the nuclear power plant working principle and hope you will find it informative. The breaking up of nuclei of heavy atoms (U235 or Th232) into two nearly equal parts with the release of a huge amount of energy is known as nuclear fission. The release of a
Working Principle of Hydroelectric Power Plant A power plant that utilizes the potential energy of water for the generation of electrical energy is known as a hydroelectric power plant. Hydroelectric power plants are generally located in hilly areas where dams can be built easily, and large water reservoirs can be made. In a hydropower plant,
