ELECTRICAL WORK SHOP PRACTICE LABORATORY

LAB IN-CHARGE: Sri. G.B. Sankara Rao
LAB TECHNICIAN: Sri. Y. Srinivasa Rao
LABORATORY AREA: 131 sq. meters

To develop practical workshop skills in the students.

• Knowledge and Comprehension
  The course is designed to provide students a widespread knowledge and understanding of the workshop tools and other facilities. The indispensable and pervasive knowledge of electrical wiring.
• Applications and Analytical Skills
  To grasp the applications of workshop equipment, wiring accessoriesimportance in the practical field.

COURSE OUTLINE:

Concepts in electrical safety, safety regulations, earthing concepts, electrical shocks and treatment.

Electrical Wiring: voltage and current measurement, transformer windings (low voltage: 6,9 and 12 volts), motor and generator windings (concept only).

- The main aim of this lab is students should acquire the knowledge of fans, tubelights, compoundterminals, transformer etc ..
- Students should be famililier to all domestic terminals.
