Pre-Requisite Knowledge

Electro-Mechanical Workshop

Summary of Content

This module provides the student with the knowledge on generation of electrical power by conventional and non-conventional methods. An understanding of the concepts on fundamentals of illumination and the design of lighting schemes. On completion of this module the students will gain knowledge on the various electrical heating and welding methods used in industries. In addition, the module gives detailed study of several Electric drives and their application to electrical traction systems

Syllabus

The taught syllabus will cover the following areas: Conventional and Non-Conventional Source Of Energy Generation of electrical power byconventional methods (thermal plant based on fossil fuel and nuclear), generation from wind, and solar sources. Electric Drives And Their Industrial Applications Introduction - motor selection and related factors - loads - types - characteristics - steady state and transient characteristics - load equalization - industrial applications - modern methods of speed control of industrial drives. Electric Traction Introduction - requirements of ideal traction system - supply systems - mechanics of train movement - traction motors and control - multiple units - braking - current collection systems Illumination Nature of light, visibility spectrum curve of relative sensitivity of human eye and wave length of light Definition: Luminous flux, solid angle, luminous intensity, illumination, luminous efficiency Laws of illumination - luminous efficacy-photometry- lumen or flux method calculation Electric lamps-flood, street lighting-design of choke Heating Heating methods Resistance heating - direct and indirect resistance heating, electric ovens, their temperature range, properties of resistance heating elements, domestic water heaters and other heating appliances and thermostat control circuit Induction heating- principle of core type and coreless induction furnace Electric arc heating- direct and indirect arc heating, construction, working and applications of arc furnace Infra-red heating and its applications Microwave heating Welding Welding method Principles of resistance welding, types - spot, projection seam and butt welding and welding equipment used Principle of arc production, electric arc welding, characteristics of arc; carbon arc, metal arc, hydrogen arc welding method of and their applications. Power supply required

Learning Outcomes

On completion of this module the student should be able to:1. Describe the different schemes for generation of electrical power by conventional and non- conventional methods(AM1, AM4)2. Apply the fundamentals of illumination and illumination methods for designing lighting schemes for different internal and external lighting applications (AM1, AM7)3. Contrast and compare the various electrical heating methods based on working principle, efficiency and losses (AM1, AM4)4. Describe the various types of electric welding methods (AM1)5. Propose suitable speed control methods for DC and AC motors for a given application (AM1, AM7)6. Outline the characteristics and applications of Electrical Traction systems (AM1)

Teaching / Learning Strategy

The main teaching method will be based on lectures. The students will be expected to perform directed reading exercises and self-learning exercises on topics related to Utilization of Electrical Power. Tutorials will be used to reinforce the module material and to discuss the issues raised by the directed reading.
