CHAPTER ONE INTRODUCTION 1.1 BACKGROUND OF THE STUDY Electricity is the most useful form of energy and constitutes one of the critical resources for modern life‚ poverty reduction and economic growth of any nation. Yet‚ for the past three decades‚ inadequate of electricity has been a regular feature in Nigeria‚ a country with about 150 million people. The electricity industry‚ dominated by National Electric Power Authority (NEPA) and later succeeded by the Power Holding Company of Nigeria (PHCN)

The resinous project of Rajasthan‚ the Super Thermal Power Station‚ and Suratgarh is situated near village Thukrana about 27 km. from Suratgarh city in sriganganar district. The site was considered an ideal location for setting up a thermal power station due to availability of land‚ water‚ transmission line and cheap labour. A total land area of 5029 bighas been acquired for the power station and 12 km. long constructed from national highway no. 15near birdhwal railway station to plant site. A

INTRODUCTION Tachogenerator is an electromechanical device which generates an electrical output directly proportional to the speed of the rotating systems. Tachogenerators are basically transducers. This transducer converts the speed of rotation directly into electrical signal. The angular speed is converted into a directly dependent voltage signals. The voltage thus generated is fed to a speedometer for speed measurement and /or used as a feedback signal for controlling the speed of a rotating

Saturable-Core Reactor (Saturable Reactor) I. Description A saturable reactor in electrical engineering is a special form of inductor where the magnetic core can be deliberately saturated by a direct electric current in a control winding. Once saturated‚ the inductance of the saturable reactor drops dramatically. This decreases inductive reactance and allows increased flow of the AC current. II. Function/Operation Figure 1. This scheme controls the output voltage by varying the impedance

CHAPTER I ------------------------------------------------- INTRODUCTION 1.1 Introduction Portable electronic devices are very popular nowadays. As the usage of these portable electronic devices is increasing‚ the demands for longer battery life are also increasing. These batteries need to be recharged or replaced periodically. It is a hassle to charge or change the battery after a while‚ especially when there is no power outlet around. Therefore‚ our team is inspired to design a wireless
