Electrical and Electronics Engineering Laboratory:

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.

Relay and High Voltage Lab

Quick Stats:

Today, the quality of life has reached such a state, that our living is practically unthinkable without electricity. Electricity is, perhaps, the third most important commodity, coming next only to air and water, for the existence of life. All of us are aware that load centers are usually far away from the generating stations, which are located in remote areas depending on the type of generation. To avoid unnecessary losses over long distances, power is invariably transmitted at higher voltages. In fact, the country is entering a stage where transmission has reached Ultra High-Voltage (UHV) levels. All this necessitates the development of appropriate insulation materials and their use in High Voltage power apparatus. Their assessment calls for a High-Voltage laboratory. A high-Voltage laboratory needs to be established to carry out fundamental studies on insulating materials, to carry out the performance evaluation of proto types and also to assess the condition of High-Voltage power apparatus before their erection and installation.

Achievements

LIFI – Light Fiedelity

Li-Fi is a wireless communication technology which utilizes light to transmit data and position between devices.Li-Fi is a light communication system that is capable of transmitting data at high speeds over the visible light, ultraviolet, and infrared spectrums. In its present state, only LED lamps can be used for the transmission of data in visible light.the technology is similar to Wi-Fi — the key technical difference being that Wi-Fi uses radio frequency to induce a voltage in an antenna to transmit data, whereas Li-Fi uses the modulation of light intensity to transmit data. Li-Fi can theoretically transmit at speeds of up to 100 Gbit/s. Li-Fi’s ability to safely function in areas otherwise susceptible to electromagnetic interference (e.g. aircraft cabins, hospitals, military) is an advantage.The technology is being developed by several organizations across the globe.

Electrostatic Energized self cleaning of Cutter

Solar energy is the most abundant, easily and constantly available Renewable energy source. It is getting popular day by day and likely to be used everywhere in the near future, because of the transition of existing non-renewable energy sources to renewable energy sources and getting the advantage of save the environment.

The Indian Government aimed at achieving 20GW capacity by 2022, but it has been achieved 4 years earlier than as per the schedule and increased their aim to generate 100GW power using Solar Energy. One of the main problems with plant is that the accumulation of dust particles on the solar panels which causes the reduction in efficiency of the generation.

The current available methods to clean solar panels require man power and huge amount of water and very expensive cleaning equipment. But the scarcity of water is increasing day by day in the regions where the solar plants likely to be installed.

In order to avoid unnecessary waste of water and any kind of abrasion on the panels while using brushes or robots while cleaning. We have developed Electron Deflector (ED) screens for cleaning purpose. When high AC voltage is applied to the ED screen the dust particles gets charged and levitates towards the edges of the screen/panels and their by removing the dust on the solar panels.
