Welcome to Virtual Labs
Physical distances and the lack of resources make us unable to perform experiments, especially when they involve sophisticated instruments. Also, good teachers are always a scarce resource. Web-based and video-based courses address the issue of teaching to some extent. Conducting joint experiments by two participating institutions and also sharing costly resources has always been a challenge. With the present day internet and computer technologies the above limitations can no more hamper students and researchers in enhancing their skills and knowledge. Also, in a country such as ours, costly instruments and equipment need to be shared with fellow researchers to the extent possible.
The armature of the DC motor is fed from a (controlled) three phase thyristor rectifier. The DC voltage to motor field is also provided by a similar controlled rectifier. All the interconnections of the components are made inside the panel. A measurement card is enclosed inside the panel, which is used to measure and scale down the voltages and currents of the motor and generator.
