e. Use Flash/Animations to explain various theorems in circuit analysis

f. Guide student(s) in undertaking micro-projects.

12. SUGGESTED MICRO-PROJECTS

Only one micro-project is planned to be undertaken by a student that needs to be assigned to

him/her in the beginning of the semester. In the first four semesters, the micro-project are

group-based. However, in the fifth and sixth semesters, it should be preferably be individually

undertaken to build up the skill and confidence in every student to become problem solver so

that s/he contributes to the projects of the industry. In special situations where groups have to

be formed for micro-projects, the number of students in the group should not exceed three.

The micro-project could be industry application based, internet-based, workshop-

based, laboratory-based or field-based. Each micro-project should encompass two or more

COs which are in fact, an integration of PrOs, UOs and ADOs. Each student will have to

maintain dated work diary consisting of individual contribution in the project work and give a

seminar presentation of it before submission. The total duration of the micro-project should

not be less than 16 (sixteen) student engagement hours during the course. The student ought

to submit micro-project by the end of the semester to develop the industry oriented COs.

A suggestive list of micro-projects are given here. Similar micro-projects could be

added by the concerned faculty:

a. Power / distribution transformer : Prepare chart showing three phase power /

distribution transformer.

b. Neutral grounding: Collect specification from different manufacturers and prepare

report.

c. Sub-station equipments: Collect specification from different manufacturers and

prepare report.

d. Gas Insulated Substation: Collect photographs with details of Gas Insulated

Substation and identify different parts (specification, application, cost, features,

various learning outcomes in this course:

a. Demonstrate students thoroughly before they start doing the practice.

b. Encourage students to refer different websites to have deeper understanding of the

subject.

c. Observe continuously and monitor the performance of students in Lab.


Only one micro-project is planned to be undertaken by a student assigned to him/her in the

beginning of the semester. S/he ought to submit it by the end of the semester to develop the

industry oriented COs. Each micro-project should encompass two or more COs which are in

fact, an integration of practicals, cognitive domain and affective domain LOs. The micro-

project could be industry application based, internet-based, workshop-based, laboratory-based

or field-based. Each student will have to maintain dated work diary consisting of individual

contribution in the project work and give a seminar presentation of it before submission. The

total duration of the micro-project should not be less than 16 (sixteen) student engagement

hours during the course.

In the first four semesters, the micro-project could be group-based. However, in higher

semesters, it should be individually undertaken to build up the skill and confidence in every

student to become problem solver so that s/he contributes to the projects of the industry. A

suggestive list is given here. Similar micro-projects could be added by the concerned faculty:

Electrical Engineering /Electrical Power System Sixth

1. RATIONALE

The pressure of Technological development in all sectors has increased the demand of

electrical energy which varies in all 24 hours of day. Under this scenario, the power system

network operates in a stressed condition. Effective management of generation, transmission

and distribution of electrical power is necessary for optimal system operation, for loss

minimization and to avoid the unwanted power cuts. This course makes the diploma holder

well aware of power system operation as well as control and optimum load dispatch analysis.

The diploma engineers working in power sector, while undertaking major activities related to

transmission and distribution systems they should be able to interpret significance of the

activities assigned to them. For example, they should be aware of active and reactive power

control strategies/mechanisms, and methods to ensure power system stability. They should

also be aware of load flow studies and load dispatch. Hence, this course is designed to

develop awareness about these concepts in diploma pass outs so that they may ensure power

system stability. Thus this course is important for diploma electrical engineers who wish to

work in power generation, transmission and distribution companies.

VI– Semester Course Curriculum

Course Title: Maintenance of Transformers and Circuit Breakers

(Course Code: ...................)



1. RATIONALE

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

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

Maharashtra. These require regular maintenance to prevent frequent break downs. Most of the

industries and big commercial installations have their own substations , also require

maintenance of transformers and circuit breakers on regular basis. Power companies also

needs the maintenance of the same through private agencies. Thus there is huge demand for

maintenance of transformers and circuit breakers.

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 capital

investment.
