Voltage Structure of Energy Electric System

Voltage Structure of Energy Electric System: An Voltage Structure of Energy Electric System, even the smallest one, constitutes an electric network of vast complexity. The one factor that determines the system structure more than any others is system size. We shall not here enter into a discussion of the reasons of economical, political, historical, and […]

Energy Efficiency

Energy Efficiency: Energy Efficiency is available in various forms from different natural sources such as pressure head of water, chemical energy of fuels, nuclear energy of radioactive substances etc. All these forms of energy can be converted into electrical energy by the use of suitable arrangement. In this process of conversion, some energy is lost […]

Sources of Energy

Sources of Energy: Since electrical energy is produced from energy available in various forms in nature, it is desirable to look into the various sources of energy. These Sources of Energy are : (i) The Sun (ii) The Wind (iii) Water (iv) Fuels (v) Nuclear energy. Out of these sources, the energy due to Sun […]

Voltage Current Characteristics

Voltage Current Characteristics: According to their terminal Voltage Current Characteristics, electrical Sources of Energy are categorised into ideal voltage sources and ideal current sources. Further they can be divided into independent and dependent sources. An ideal voltage source is a two-terminal element in which the voltage Vs is completely independent of the current is through […]

Energy Conservation

Energy Conservation: Energy conservation is the cheapest new source of energy. We should resort to various conservation measures such as cogeneration (discussed earlier), and use energy efficient motors to avoid wasteful electric uses. We can achieve considerable electrical power savings by reducing unnecessary high lighting levels, oversized motors, etc. A 9 W compact fluorescent lamp (CFL) […]
