Due to inherent linearity and wide operating range Rogowski Coil (RC) can be used as a current transducer in electrical power system. This paper presents use RC for accurate measurement of secondary current to prevent under reaching of the distance relay caused by saturation of conventional Current transformer (CT).Conventional CT, lumped parameter RC with integrator and distance protection scheme...
In India, more than 200 million people live in rural areas without access to grid-connected power. A convenient & cost-effective solution would be hybrid power systems which can reduce dependency on grid supply, improve reliability. For a typical domestic load a solar –wind hybrid system is designed with charge controller to charge a conventional battery. To optimize system efficiency, a simple...
Low impact renewable energy technologies offer important benefits compared to conventional energy sources, such as fossil fuels or nuclear power. Renewable-energy resources are abundant; worldwide, and are unevenly distributed. They are capable of producing around one-thousand-times more energy than is released today by all fossil fuels consumed. However due to their uncertainty different kinds of...
Over 1.6 billion people living in the rural areas of the poorest regions of the world, especially in sub-Saharan Africa and South Asia lack access to modern forms of energy services. In addition, currently used sources of energy for cooking and heating (wood, crop residues, charcoal, etc.) are a serious source of indoor pollution, causing environmental and health problems and contributing to deforestation...
Energy in general and electrical energy in particular is not only at the center of sustainable development, but also at the center of development itself. Thus energy is critical for sustainable development because it is not only necessary for economic development, but also because this necessity drives societies towards environmentally unsound energy use and could severely compromise the planet itself...
