Design and construction of 36W automatic solar street light using Solar panel, charge controller, led and with battery CHAPTER ONE INTRODUCTION 1.1Background Information Electricity is a general term comprising of a variety of phenomena resulting from the presence and flow of electric charge. These include many phenomena, such as lightning, static electricity, and the flow of electrical current in a cable. In addition, electricity comprises less familiar concepts such as the electromagnetic f...
Abstract Induction machine account for about 60percent of the electrical consumption in industrial countries; hence a huge energy savings could be achieved by even a small increment in the machine efficiency. Improving the designs of induction machines requires accurate quantification of the machine losses. A significant portion of the losses in electrical machine is caused by the core losses in the magnetic materials. The physical mechanism of core losses is still an open problem, and most o...
