Not every technical institute in India has access to all the educational facilities existing in the IITs, more so the lab facilities. The lack of such facilities should not undermine the students studying in these institutes. The Indian Government is trying hard to ensure that all their students get quality education irrespective of where the study. The virtual Machine and Instrumentation workbench is a novel idea born out of the need for free and straightforward access to better facilities for all the engineering students, whether B. Tech or M. Tech.
The virtual Machine and instrumentation workbench is a grand venture of the National Mission on Education through Information and Communication Technology (NMEICT) of the Ministry of Human Resource Development (MHRD), Government of India to ensure that the students of each and every technical institute of India get an easy and effective access to the expensive laboratory instruments through virtualisation of the lab equipments in IITs. This venture provides any student with the opportunity to operate the instruments unavailable in his/her institute and conduct practical experiments from the comfort of his home through the medium of internet. This virtual Machine workbench is created and maintained by the P.G. Machine Lab of Department of Electrical Engineering at IIT Roorkee and caters to the need of Electrical Engineering students. The complete menu of virtual Machine experiments encompasses almost the entire range of experiments covered in the technical institutes of India at B. Tech and M. Tech level. As of now, we have concentrated more on generator related experiments.
The list of experiments is as follows:
1. To determine the efficiency of a dc motor by loss summation method(Swinburne's test).
2. Speed Control of DC motor by varying armature and field resistance.
3. To perform speed control of DC motor by using Ward- Leonard Method of speed control.
4. To study the Load Characteristics of DC shunt generator.
5. To study Magnetisation Characteristics of DC shunt generator.
6. speed control of Slip ring induction machine.
7. Determination of Transformer equivalent circuit from Open Circuit and Short Circuit Test.
The interface of the experiments has been designed keeping in mind the nature of the experiments to make it as real as possible. A lot of effort has gone into making the application extremely user friendly so that students face little difficulty in carrying out the experiments. After the experiments are conducted, the students are presented with a multiple choice quiz to refresh their knowledge on the subject. Also, the theory of the experiment conducted is explained briefly yet accurately in the report to get an in-depth understanding of the experiment. The setup for the experiment is also visible throughout the experiment through the use of a camera that can be controlled by the user.
For a student to try out any experiment, he/she should first get himself/herself registered on the website. After registration, they can choose a time slot offered for the experiment. If it is available, then the user is allowed to conduct the experiments during the allocated slot. Plenty of slots are available for the students so that each one of them can avail the opportunity to try out the experiments.
