Circular debt‚ Rental Power Projects (RPPs)‚ Independent Power Projects (IPPs)‚ NEPRA‚ PPIB‚ Discos‚ power outages‚ etc are casually floated around every now and then. Moreover‚ WAPDA and KESC have become words of ridicule for residents in small hamlets and all the way to metropolitan cities. It seems that‚ today‚ electricity can bring political parties into power or even consign it into the wilderness. With the advent of the new government

Importance of electrical services in buildings Electricity has been part of our lives. It has brought many things that surely have made many wonders and life would seem so hard without it. Electricity powers our light‚ heating‚ electronic appliances such as computers and television‚ and a host of essential services that we take for granted. However‚ electricity has much more important aspects because it is a fundamental feature of all matter. Electricity is the force that holds together the

issue of electric car has been arising nowadays. But many of us never really find a true example of the uses of electric cars in everyday life. From the article "Electrical Engineering"‚ an Australian built his own electric car from a second hand Porsche. The article proves that having a private electric cars is no longer a dream. But do all people know the good things and the bad things about having a private electric car? Now‚ what electric vehicles really are? Simply put‚ electric vehicles

Fig 1.1 Block diagram of an Electrical Drive The advancement in electric drive system is very much related to the development in the power semiconductor devices technology. The introduction of the Silicon Controlled Rectifier (SCR) in 1957 has initiated the application of solid state devices in power converters. The development of

An electric field surrounds all electrically charged particles. With electric fields‚ one can determine the effects of all of the charges in the environment. In this lab entitled “Electric Fields and Potential Mapping”‚ the main goal obtained was to examine and deliberate the effects of an electric field and electric potential. Examples of some effects of electric fields include resultant forces‚ changes in motion‚ changes in current flow‚ etc. By using conductive paper connected to a power supply

to take concrete actions to involve the private sector in energy infrastructure projects by the early 1980s. However‚ the lack of legal and regulatory framework underlying a consistent reform strategy stalled the private sector involvement in the power industry projects. Indeed the subsequent legal disputes resulted in an overall negative impression of the investment climate in Turkey. Based on the lessons learned over the last 25 years‚ a more structured transformation process is in the making.

alternating current transmission system (FACTS) is a system composed of static equipment used for the AC transmission of electrical energy. It is meant to enhance controllability and increase power transfer capability of the network. It is generally a power electronics-based system. FACTS is defined by the IEEE as "a power electronic based system and other static equipment that provide control of one or more AC transmission system parameters to enhance controllability and Technology Transmission

In this essay I am going to be telling you about to what extent electric cars solve the fuel crisis. The critical steps are: 1. Evolve autos from gasoline/diesel to hybrid to plug-in hybrid. 2. Develop a battery that can run 200 miles on a 10-minute recharge. 3. Strengthen Briton’s electrical distribution system. 4. Recharge cars in garages‚ public places and service stations. 5. Build nuclear power plants to enlarge the supply of electricity. 6. Use all alternate sources of energy‚ i.e. wind
