LABORATORIES – UG

The Department of Electrical & Electronics Engineering has identical spacious premises for each laboratories including Electrical Machines Lab, Power Electronics Lab, Electrical circuits Lab, Power Electronics Lab, Control &Instrumentation Lab and Power System Simulation Lab etc.

The Electrical Machines Laboratory supports teaching, research and consultancy work on Electrical machines and drives. Through hands-on experiments with real machines, students gain practical experience on transformers and various types of machine drives. The laboratory can also be used for project work related to electrical machines and energy conversion.

The four main purpose of an electrical machines laboratory are

  • To provide the student with practical knowledge of handling the electrical machines.
  • To correlate the theoretical classroom treatment with actual machine characteristics.
  • To demonstrate the most suitable testing techniques.
  • To educate engineer researchers and to conduct research in all aspects of electrical and electromechanical energy conversion.

The laboratory has

  • D.C. Motors and Generators
  • 3 Phase Induction Motors, (Squirrel cage and slipring type)
  • 3 Phase Synchronous machines
  • Single phase & 3 Phase Transformers
  • 1 Phase Induction Motors (Various types)
  • Cut sections of actual machines like
  • D.C. motors
  • Generators
  • A.C. motors
  • Generators, associated with well-designed panels and informative displays.

The Machines laboratory is supported with large capacity three phase A.C. to D.C. rectifier unit to supply D.C. power. The machines laboratory is well equipped with all kinds of measuring instruments also.The laboratory is utilized for conducting various practical courses like DC Machines Lab, AC Machines Lab, Transformers Lab and Controls Lab. The experiments like Load test, Swinburne’s test and speed control are done on DC Motors. DC generator setup is used to conduct Open circuit and Load characteristics, Hopkinson’s test and transfer function. Open Circuit & Short Circuit Test Sumpner’s Test, Polarity test and Load test were conducted on single phase and three phase transformers. Single phase & three phase Induction Motors were used to conduct Load test, Speed Control, No load & Blocked Rotor test. The experiments like Voltage regulation, Slip test, Load test and V-Curve & Inverted V-Curve Characteristics can be conducted on Synchronous machines

Power electronics studies the application of semiconductor devices to the conversion and control of electrical energy. The field is driving an era of rapid change in all aspects of electrical energy. The Power Electronics Laboratory seeks to enhance general material with practice and hands-on experience. The laboratory course provides instruction in general lab practices, measurement methods, and with the design and operation of several common circuits relevant to the field of power electronics. It also provides experience with common components such as motors, batteries, magnetic devices, and power semiconductors.

In the Electrical Circuit Lab students can create their own electrical circuits and do measurements on it. In the circuits lab the students, with the use of resistors, light bulbs, switches, capacitors and coils, powered by a AC/DC power supply or batteries measurements were made in DSO or CRO , ammeter, voltmeter, wattmeter and an ohmmeter.

Control & Instrumentation laboratory provides a “hands-on” environment that is crucial for developing students ‘understanding of theoretical concepts. Control & Instrumentation laboratory is housed with different instruments like temperature measurement, level detection, pressure measurement, flow measurement etc. On different panels or rigs these are arranged in different control configurations to achieve specific control objectives.

Is a computer model that mimics the operation of a real or proposed Power system. Simulation tool helps in validating the ideas and new concepts which born’s in an engineer’s mind which seeks for solution to a problem. Sophisticated Computer programs are used in Power System Simulation Laboratory for the purpose of analysis and design in the following domains.
