Electrical & Electronics Engineering Labs
The Electrical Engineering deals with the study and application of electricity, electronics and electromagnetism, which includes all large-scale electrical systems mostly, power transmission and motor control. Electrical Engineering has gone from simple electric circuits of Edison and Tesla through Rocket science of Bode and Nyquist to the complexity of IC, Satellites and Communication network. The demand of electrical energy in our country is increasing at a very fast rate and this necessitates the need to generate more power. Thus, the role of electrical engineers becomes all the more important in today’s scenario.
We are equipped to provide prospective engineers with the necessary training and knowledge to enable them to make a meaningful contribution in this area. Initially, the programme provides students with a broad base on which their specialist knowledge can be built. The latter years have been designed to produce professional engineers with a good working knowledge of analogue, digital and power electronics, electrical machines and power system with the emphasis on applications. The Department has an excellent infrastructure to promote a congenial academic environment to impart quality education with well-equipped laboratories and a team of qualified and dedicated faculty members.
The Department has a well developed Research & Development Cell guided by dedicated faculty members. It also has adequate skilled and self-motivated technical staff. We have developed Industry Academia Cell also. The Department has strong tie ups with industry and one of the advantages this holds for our students is the fact that they are in demand; not only in the local market, but internationally as well.
