Questions
Which syllabus is followed?
The current AKTU (Dr. A.P.J. Abdul Kalam Technical University, Lucknow) B.Tech syllabus of Switchgear and Protection Lab (Electrical Engineering, Semester 7). If your university or college follows a different syllabus, the centre teaches from your own university syllabus.
How is the lab assessed?
By the experiment performed, readings or output, the practical record file and a viva voce, as in the AKTU internal and external lab examination.
Do I need to maintain a record file?
Yes. The centre helps you write each experiment with aim, apparatus, theory, circuit diagram, observations, calculations, result and precautions.
