Electrical Technology ( ET ) - Introduction & Scope :

The subject of Electrical Technology ( ET ) is one of the oldest scientific disciplines encompassing all facets of human life. It comprises a major component of classical Engineering disciplines. Right from the old days of Stone ages to the current modern age, Electricity has continued to fascinate the intellect of human beings. From manifestation of fire to lightnings and the discovery of the cause of lightning, mankind has always been inquisitive to know more about it.

 

Further to it various experiments were conducted by philosophers and scientific researchers like Benjamin Franklin, Michael Faraday, Coulombs and many others. All of them built upon and leveraged upon the outcome of their predecessor's research, thus, leading us to where we stand today. Electrical Technology ( ET ) builds upon the principles of Physics ( the study of natural phenomenon and  nature ) and the analysis of the atomic constitution, through understanding of behaviour and interactions of sub - atomic particles like electrons, protons, neutrons and others with each other.

 

We are now able to tame and harness most of our energy needs from the knowledge that we have acquired today. As we learn more about the potential and scope of Electrical energy we discover more information and this science continues to evolve.

​

Electrical Technology ( ET ) has significant impact to the existing power generation technology set up that covers almost every industry sector and domain. Without harnessing Electrical Energy, today's human existence is very difficult. The dependence has now become quite inalienable. Right from generation of electric current or common electricity to its distribution, transmission and consumption, a lot of Engineering and research efforts have already been invested.

 

A few of the key common components, concepts, and, tools of Electrical Technology ( ET ) are :

 

Series / Shunt Motors,

Alternating Currents - AC, 

Direct Current - DC,

Teaching Activities :
The teaching and training activities have to be conducted in classroom, laboratory / workshops and field visits. Students should be taken to field visits for interaction with experts and to expose them to the various tools, equipment, materials, procedures and operations in the workplace. Special emphasis should be laid on the occupational safety, health and hygiene during the training and field visits.

Classroom Activities :
Classroom activities are an integral part of this course. Interactive lecture sessions, followed by discussions should be conducted by trained teachers. Teachers should make effective use of a variety of instructional or teaching aids, such as audio-video materials, colour slides, charts, diagrams, models, exhibits, hand-outs, online teaching materials, etc. to transmit knowledge and impart training to the students.

Practical Work In Laboratory / Workshop : 
Practical work may include but not limited to hands-on-training, simulated training, role play, case based studies, exercises, etc. Equipment and supplies should be provided to enhance hands-on learning experience of students. Only trained personnel should teach specialized techniques. A training plan that reflects tools, equipment, materials, skills and activities to be performed by the students should be submitted by the teacher to the Head of the Institution.

Field Visits / Educational Tours : 
In field visits, children will go outside the classroom to obtain specific information from experts or to make observations of the activities. A checklist of observations to be made by the students during the field visits should be developed by the teachers for systematic collection of information by the
students on the various aspects. Principals and Teachers should identify the different opportunities for field visits within a short distance from the school and make necessary arrangements for the visits. At least three field visits should be conducted in a year.

Skill Assessment ( Practical ) : 
Assessment of skills by the students should be done by the assessors / examiners on the basis of practical demonstration of skills by the candidate. Practical examination allows candidates to demonstrate that they have the knowledge and understanding of performing a task. This will include hands - on practical exam and viva voce. For practical, there should be a team of two evaluators. The same team of examiners will conduct the viva voce.

​

Project Work :
Project Work ( individual or group project ) is a great way to assess the practical skills on a certain time period or timeline. Project work should be given on the basis of the capability of the individual to perform the tasks or activities involved in the project. Projects should be discussed in the class and the teacher should periodically monitor the progress of the project and provide feedback for improvement and innovation.

​

Field Visits :

Field visits should be organised as part of the project work. Field visits can be followed by a small-group work / project work. When the class returns from the field visit, each group might be asked to use the information that they have gathered to prepare presentations or reports of their observations. Project work should be assessed on the basis of practical file or student portfolio.

​

Student Portfolio :
Student Portfolio is a compilation of documents that supports the candidate’s claim of competence. Documents may include reports, articles, photos of products prepared by students in relation to the unit of competency.

​

Viva Voce :
Viva voce allows candidates to demonstrate communication skills and content knowledge. Audio or video recording can be done at the time of viva voce. The number of external examiners would be decided as per the existing norms of the Board and these norms should be suitably adopted / adapted as per the specific requirements of the subject. Viva voce should also be conducted to obtain feedback on the student’s experiences and learning during the project work / field visits.

Organisation of Field Visits / Educational Tours :
In a year, at least 3 field visits / educational tours should be organised for the students to expose them to the activities in the workplace.

Teaching Activities :
The teaching and training activities have to be conducted in classroom, laboratory / workshops and field visits. Students should be taken to field visits for interaction with experts and to expose them to the various tools, equipment, materials, procedures and operations in the workplace. Special emphasis should be laid on the occupational safety, health and hygiene during the training and field visits.

​

Classroom Activities :
Classroom activities are an integral part of this course and interactive lecture sessions, followed by discussions should be conducted by trained teachers.  Teachers should make effective use of a variety of instructional or teaching aids, such as audio-video materials, colour slides, charts, diagrams, models,
exhibits, hand-outs, online teaching materials, etc. to transmit knowledge and impart training to the students.

​

Practical Work In Laboratory / Workshop :
Practical work may include but not limited to hands-on-training, simulated training, role play, case based studies, exercises, etc. Equipment and supplies should be provided to enhance hands-on learning experience of students. Only trained personnel should teach specialized techniques. A training plan that reflects tools,
equipment, materials, skills and activities to be performed by the students should be submitted by the teacher to the Head of the Institution.

Skill Assessment ( Practical ) :
Assessment of skills by the students should be done by the assessors / examiners on the basis of practical demonstration of skills by the candidate. Practical examination allows candidates to demonstrate that they have the knowledge and understanding of performing a task. This will include hands-on practical exam and viva voce. For practical, there should be a team of two evaluators. The same team of examiners will conduct the viva voce.

​

Project Work :
Project Work ( individual or group project ) is a great way to assess the practical skills on a certain time period or timeline. Project work should be given on the basis of the capability of the individual to perform the tasks or activities involved in the project. Projects should be discussed in the class and the teacher should
periodically monitor the progress of the project and provide feedback for improvement and innovation.

​

Field Visits :
Field visits should be organised as part of the project work. Field visits can be followed by a small - group work / project work. When the class returns from the field visit, each group might be asked to use the information that they have gathered to prepare presentations or reports of their observations. Project work
should be assessed on the basis of practical file or student portfolio.

​

Student Portfolio :
Student Portfolio is a compilation of documents that supports the candidate’s claim of competence. Documents may include reports, articles, photos of products prepared by students in relation to the unit of competency.

​

Viva Voce :
Viva voce allows candidates to demonstrate communication skills and content knowledge. Audio or video recording can be done at the time of viva voce. The number of external examiners would be decided as per the existing norms of the Board and these norms should be suitably adopted / adapted as per the specific
requirements of the subject. Viva voce should also be conducted to obtain feedback on the student’s experiences and learning during the project work / field visits.

​

Organisation Of Field Visits / Educational Tours : 
In field visits, children will go outside the classroom to obtain specific information from experts or to make observations of the activities. A checklist of observations to be made by the students during the field visits should be developed by the Teachers for systematic collection of information by the students on the various aspects. Principals and Teachers should identify the different opportunities for field visits within a short distance from the school and make necessary arrangements for the visits. At least three field visits should be conducted in a year.
