COURSE INFORMATION
During the two years duration of Electrician trade a candidate is trained on professional
skills& knowledge, Engineering Drawing, Workshop Calculation & Science and Employability
skill related to job role. In addition to this a candidate is entrusted to undertake project work
and extracurricular activities to build up confidence. 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.
