Preamble: This course primarily deals with utilization of electrical energy generated from various sources. It is important to understand the technical reasons behind selection of motors for electric drives based on the characteristics of loads. Electric heating, welding and illumination are some important loads in the industry in addition to motor/drives. Another major share of loads is taken by Electric Traction. Utilization of electrical energy in all the above loads is discussed in detail in this course. Demand side management concepts are also introduced as a part of this course.

OBJECTIVES:

  • To understand the operating principles and characteristics of traction motors with respect to speed, temperature,loading conditions.
  • To acquaint with the different types of heating and welding techniques.
  • To study the basic principles of illumination and its measurement.
  • To understand different types of lightning system including design.
  • To understand the basic principle of electric traction including speed–time curves of different traction services.
  • To understand the method of calculation of various traction system for braking, acceleration and other related parameters, including demand side management of energy.
