सवाल

Are machines run by students?

Yes, under supervision, after the connections are checked by the trainer.

Is VFD practice included?

Yes, where the lab has a VFD, speed control by frequency is demonstrated and recorded.

Is this course based on the BTEUP syllabus?

Yes. The units follow the BTEUP (Board of Technical Education, Uttar Pradesh) diploma syllabus. If your polytechnic follows a different board or a revised scheme, the centre teaches your own syllabus.
