CHAPTER 4TRANSFORMERS

4.1 INTRODUCTION

Electric energy processing involves conversion, transfer, transmission, control, and storage of energy. Sources of energy can be converted into many forms (such as chemical, mechanical, electrical, sunlight, and wind, and audio, visual, or otherwise) including data processing by computer. This energy when transformed can be transferred and distributed. Potential energy resulting from rainfall in lakes and rivers can be converted to kinetic energy of seawater and tides, which could supply 50 percent of total world energy demand. Other forms of energy exist, such as kinetic energy of wind and solar. Other forms of energy include geothermal energy and fossil fuels such as oil, coal, and gas. Mechanical to electrical energy as simplified energy processing supply chain is shown in Figure 4.1.

Energy sources that are transformed and transferred are sent from the source to the consumer in different forms as needed. They are easily measurable, observable, and controllable to meet industrial, commercial, and residential loads. The creative and associative voltage and current achieve the production of power transfer. For mechanical power force and velocity are associated with mechanical power. But what is the link that enables one form of power to ...
