1. RATIONALE

As Physics is the mother of all engineering disciplines, students must have some basic knowledge on physics to understand their core engineering subjects more comfortably. Accordingly, in reviewing the syllabus, emphasis has been given on the principles, laws, working formulae and basic ideas of physics to help them study the core subjects. Complicated derivations have been avoided because applications of the laws and principles of physics are more important for engineering students. As Physics is considered as basic science, its principles, laws, hypothesis, concepts, ideas are playing important role in reinforcing the knowledge of technology. Deep thought is given while selecting topics in physics. They are different for various branches of engineering. This will provide sound background for self-development in future to cope up with new innovations. Topics are relevant to particular program and students will be motivated to learn and can enjoy the course of Physics as if it is one of the subjects of their own stream. Engineering, being the science of measurement and design, has been offspring of Physics that plays the primary role in all professional disciplines of engineering. The different streams of Physics like Optics, Acoustics, Dynamics, Semiconductor Physics, Surface Physics, Nuclear physics, Energy Studies, Materials Science, etc provide Fundamental Facts, Principles, Laws, and Proper Sequence of Events to streamline Engineering knowledge. Note:- Teachers should give examples of engineering/technology applications of various concepts and principles in each topic so that students are able to appreciate learning of these concepts and principles. Laboratory experiments have been set up keeping consistency with the theory so that the students can understand the applications of the laws and principles of physics.




The course content should be taught and implemented with the aim to develop different types of skills leading to the achievement of the following competencies…………. Select proper measuring instrument on the basis of range, least count & precision required for measurement. Analyze properties of material & their use for the selection of material mostly applicable for engineering users.. Identify good & bad conductors of heat and proper temperature scale for temperature measurement Identify, analyze, discriminate and interpret logical sequence of field problems with the study of physics.

power using Thermal (Coal), Hydro, Nuclear, Solar, Wind, Diesel and Other renewal energy

sources. These types of power plants need highly skilled technicians who are capable of

operating various control equipment to supply uninterrupted power. This course attempts to

develop the basic cognitive skills required to take appropriate decisions to maintain the various

generating and auxiliary equipment of power plants. Moreover, the safety precautions required to

be followed by the engineering diploma holders in various power plants is also included in this

course.

COURSE CURRICULUM

COURSE TITLE: ENERGY CONSERVATION & AUDIT





Semester

1. RATIONALE

The consumption of energy is increasing day by day. One way to cope up with the increase in

energy demand is to increase the production of energy which demands more investment and

the other way is to conserve the energy because energy conserved/saved is energy generated.

Energy conservation means reduction in energy consumption but not compromising with the

quality or quantity of energy production. Essential theoretical and practical knowledge about

the concept of energy conservation, energy management, different approaches of energy

conservation in industries, economic aspects of energy conservation project and energy audit

and measuring instruments in commercial and industrial sector will be achieved by this

course.

Maintenance of Transformer and Circuit Breaker Course Code:3360907



COURSE CURRICULUM

COURSE TITLE: MAINTENANCE OF TRANSFORMER AND CIRCUIT BREAKER




1. RATIONALE

Power system consists of a number of transformers, circuit breakers installed at substations

including poll mounted distribution transformers whose numbers are in thousands only in

Gujarat. These require regular maintenance to prevent permanent break down. Most of the

industries and big commercial installations such as big institutes/hotels/complexes/hospitals

that have their own substation also require maintenance of transformers and circuit breakers

on regular basis. Most of the big cities are now establishing their own Metro railways. Indian

Railways and city metros also have their own substations where transformer and circuit

breakers are installed. Power companies also off load their maintenance work of distribution

transformers and circuit breakers to private agencies. Thus there is huge demand for

maintenance of transformers and circuit breakers.

Transformer and Circuit Breakers are one of the two electric equipment who operate at

highest possible voltage i.e up to the level of 400 KV (generators and motors normally

operate up to 33 KV Class). Moreover in transformers and circuit breakers current breaking

and making takes place with full power (In transformer it happens in on load tap changer).

Because of these conditions of very high voltage operations and breaking and making of full

power current, insulating oil of transformers and circuit breakers is subjected to deterioration.

Contacts of the circuit breaker are also subjected to deterioration due to formation of arcs.

Because of these reasons these equipment require regular maintenance.

This course will enable the diploma pass out student to understand the concepts, principles

and acquire basic skills of testing and maintenance of transformers and circuit breakers. There

is a huge scope of self employment in this area with very less investment of capital.

2. COMPETENCY



Maintain transformers and circuit breakers.

3. COURSE OUTCOMES




i. Undertake /apply preventive maintenance

ii. Maintain power and distribution transformers.

iii. Commission different types of transformers

iv. Maintain different types of circuit breakers

COURSE CURRICULUM

COURSE TITLE: ELECTRIFICATION OF BUILDING COMPLEXES





1. RATIONALE

With the revolutionary changes in the building construction, advent of new building materials

and electrical fittings and accessories there is an increase in demand for specialists in

electrification of high rise-multistoried building and commercial complexes. Therefore a

limited exposure to electrification of small building is not sufficient and this subject needs to

be taught as a specialized subject. This course will provide knowledge about electrification of

high rise buildings and complexes. Studying this course will enable the diploma pass outs to

plan, design, and estimate and execute the electrification of multistoried buildings and

commercial complexes independently and professionally as per IE rules. If proper skills are

developed then pass outs may start their own business of electrification of building

complexes, which is very profitable and growing business and requires very less investment.

2. COMPETENCY



Applying IE rules, undertake the electrification of multistory buildings and

commercial complexes.

3. COURSE OUTCOMES

The theory should be taught and practical should be undertaken in such a manner that students


domains to demonstrate the following course outcomes:

i. Interpret plan and wiring diagrams of electrification of buildings and complexes.

ii. Calculate the average and peak power requirement of building complexes.

iii. Test a given wiring installation of a building and prepare test report.

iv. Test wiring installation of a multistoried building and commercial complexes.

v. Estimate the materials and cost of electrification for different buildings.

vi. Test the safety devices in a multistoried building and commercial complexes.
