The Broad components covered during the course are given below: FIRST YEAR: In this year the trainee learns about safety and environment, use of fire extinguishers, artificial respiratory resuscitation to begin with. He gets the idea of trade tools & its standardization, identifies different types of conductors, cables & their skinning & joint making. Basic electrical laws like Kirchhoff’s law, ohm’s law, laws of resistances and their application in different combinations of electrical circuit are practiced along with laws of magnetism. The trainee practices on circuit for single phase and poly-phase circuits for 3 wire /4 wire balanced & unbalanced loads. Skilling practice on different types & combination of cells for operation and maintenance is being done. Wiring practice with installation of different accessories like ICDP switch, distribution fuse box and mounting energy meters are practiced as per IE rules for hostel/residential building, workshop and its fault detection are done by trainee. The trainee will practice for pipe & plate earthing. Different types of light fitting are to be done like HP/LP mercury vapour and sodium vapour are prominent. The trainee will practice on different types of measuring instruments like multimeter, wattmeter, energy meter, phase sequences meter, frequency meter, for measurement of electrical parameters in single & three phase circuits. He will gain skill on range extension, calibration and testing of meters. Practice for dismantling, assembling and testing of heating element equipment, induction heating equipment, grinding machines and washing machines will be done by trainee. Skill will be gained on transformer for operation, efficiency, series parallel operation, replacement of transformer oil and combination of single-phase transformers for 3 phase operation. The trainee will practice on winding of small transformer. SECOND YEAR: In this year the trainee will study the details of electrical rotating machines viz. DC machines, induction motors, alternators & MG sets and practice on them. The trainee will practice on determining characteristics, their performance analysis, starting, speed control and reversing direction of rotation of machines. He will practice on parallel operation & synchronization of alternators, winding practice and over hauling will be practiced for DC machine and induction motors. Practices on diodes for bridge rectifier, switching devices & amplifiers by electronic components, different wave shape generation and testing by CRO. Designing control cabinet, assembling control elements and their wiring are to be practiced. Speed control of AC/DC motors by electronic controller will be practiced. The trainee will practice on testing, analyzing and repairing of voltage stabilizer, emergency light, battery charger, UPS and inverter. He will gain knowledge of thermal, hydel, solar & wind energy systems. The trainee will practice on distribution system, domestic service line and accessories & their protection by practicing on relay and circuit breaker for operation and maintenance. 2. TRAINING SYSTEM :- GENERAL The Directorate General of Training (DGT) under Ministry of Skill Development & Entrepreneurship offers a range of vocational training courses catering to the need of different sectors of economy/ Labour market. The vocational training programmes are delivered under the aegis of Directorate General of Training (DGT). Craftsman Training Scheme (CTS) with variants and Apprenticeship Training Scheme (ATS) are two pioneer schemes of DGT for strengthening vocational training. Electrician trade under CTS is one of the most popular courses delivered nationwide through network of ITIs. The course is of two years duration. It mainly consists of Domain area and Core area. The Domain area (Trade Theory & Practical) impart professional skills and knowledge, while Core area(Workshop Calculation and science, Engineering Drawing and Employability Skills) impart requisite core skill, knowledge and life skills.After passing out of the training programme, the trainee is awarded National Trade Certificate (NTC) by DGT which is recognized worldwide. Trainees broadly need to demonstrate that they are able to:
  •  Read and interpret technical parameters/ documents, plan and organize work processes, identify necessary materials and tools;
  •  Perform task with due consideration to safety rules, accident prevention regulations and environmental protection stipulations;
  •  Apply professional skill, knowledge & employability skills while performing jobs.
  •  Check the job/ assembly as per drawing for functioning identify and rectify errors in job/ assembly.
  •  Document the technical parameters related to the task undertaken. 2.2 PROGRESSION PATHWAYS
  •  Can join industry as Technician and will progress further as Senior Technician, Supervisor and can rise up to the level of Manager.
  •  Can become Entrepreneur in the related field.
  •  Can appear in 10+2 examination through National Institute of Open Schooling (NIOS) for acquiring higher secondary certificate and can go further for General/ Technical education
  •  Can take admission in diploma course in notified branches of Engineering by lateral entry.
  •  Can join Apprenticeship programme in different types of industries leading to National Apprenticeship certificate (NAC).
  •  Can join Crafts Instructor Training Scheme (CITS) in the trade for becoming instructor in ITIs.
  • Can join Advanced Diploma (Vocational) courses under DGT as applicable.
2.3 COURSE STRUCTURE :- Table below depicts the distribution of training hours across various course elements during a period of two-years: - 2.4 ASSESSMENT & CERTIFICATION The trainee will be tested for his skill, knowledge and attitude during the period of course through formative assessment and at the end of the training programme through summative assessment as notified by the DGT from time to time. a) The Continuous Assessment (Internal)during the period of training will be done by Formative Assessment Method by testing for assessment criteria listed against learning outcomes. The training institute has to maintain individual trainee portfolio as detailed in assessment guideline. The marks of internal assessment will be as per the formative assessment template provided on www.bharatskills.gov.in. b) The final assessment will be in the form of summative assessment. The All India Trade Test for awarding NTC will be conducted by Controller of examinations, DGT as per the guidelines. The pattern and marking structure is being notified by DGT from time to time. The learning outcome and assessment criteria will be basis for setting question papers for final assessment. The examiner during final examination will also check individual trainee’s profile as detailed in assessment guideline before giving marks for practical examination. PASS REGULATION For the purposes of determining the overall result, weightage of 100% is applied for six months and one year duration courses and 50% weightage is applied to each examination for two years courses. The minimum pass percent for Trade Practical and Formative assessment is 60% & for all other subjects is 33%. There will be no Grace marks. 2.4.2 ASSESSMENT GUIDELINE Appropriate arrangements should be made to ensure that there will be no artificial barriers to assessment. The nature of special needs should be taken into account while undertaking assessment. Due consideration should be given while assessing for teamwork, avoidance/reduction of scrap/wastage and disposal of scrap/wastage as per procedure, behavioral attitude, sensitivity to environment and regularity in training. The sensitivity towards OSHE (Occupational Safety & Health Environment) and self-learning attitude are to be considered while assessing competencies. Assessment will be evidence based, comprising the following:
  •  Job carried out in labs/workshop
  • Record book/ daily diary
  •  Answer sheet of assessment
  •  Viva-voce
  •  Progress chart
  •  Attendance and punctuality
  • Assignment
  •  Project work
  • Evidences and records of internal (Formative) assessments are to be preserved until forthcoming examination for audit and verification by examination body.
