The Department of Electrical Engineering has a large number of laboratories that support its educational and research activities. In addition to the specialized equipment that each lab contains, all the labs are equipped with basic utilities such as DC and AC electric sources, voltage regulators, signal (function) generators, oscilloscopes, and analog and digital multimeters for measuring the basic quantities (voltage, current, and resistance). Labs also have a number of integrated personal computer systems to operate educational software. Every student has a good chance to have a hands-on experience and practice experimental work as the number of students per experimental station ranges from two to four only. The current departmental labs are:
Electric Machines Lab
This laboratory in the Department of electrical engineering has its purpose to educate the students in all confronts related to electrical machines. The lab is well equipped with various kinds of ac and dc machines, which provide an opportunity to students to gain skillful knowledge about the machines.
Power Systems Lab
This laboratory is intended for graduate course in allied areas of power systems. The lab is well equipped with versatile modules such as transmission line simulator and DC network analyzers. Besides these it has various electromagnetic relays and digital relays and other equipment meant for fundamental research in power system area. This core course builds a profound understanding of various utility power systems and renewable energy systems. The students will learn the principle operation and components of the generating stations followed by learning the fundamentals of low voltage distribution systems and high voltage distribution system and its challenges. Then we look at the cost of electricity and DC transmission systems.
High Voltage Lab
High voltage lab is based on a system of components made with the highest precision and can be used to build systems both for teaching and research. The assembly of a test setup is easily done and requires no special tools. The system gives highly accurate values and can even be used for calibration purposes. Modular design makes it quick and easy to setup different test circuits, allowing maximum time for experimentation. The experiments include generation and measurement of alternating voltages, direct voltages and impulse voltages. It also includes various tests like breakdown test, transformer test and PD measurement.
Electric Circuits Lab
This laboratory enables the students to understand the Fundamental Theorems and Laws useful to design electrical networks. It is designed to enable students to comprehend main characteristics of simple electronic devices such as diodes and transistors. The laboratory session is synchronized with the lecture in such a way that they complement each other. Practical circuits are built to investigate signal, bipolar transistor circuits under DC and AC conditions as well as small signal amplifiers. Filters, oscillators, operational amplifiers using discrete components are also built in this lab.
In this laboratory the students are trained to measure accurately the electrical parameters (R-L-C) using bridges. There are also experiments for the measurements of real and reactive power and energy. The goal of the lab is to learn to measure electrical quantities, investigate the properties of electrical meters, batteries and power supplies.
Logic Design Lab
The basic logic gates are the building blocks of more complex logic circuits lab. These logic gates perform the basic Boolean functions, such as AND, OR, NAND, NOR, Inversion, Exclusive-OR, Exclusive-NOR. In this lab the basic logic gates are implemented as small-scale integrated circuits (SSICs) or as part of more complex medium scale (MSI) or very large-scale (VLSI) integrated circuits. Digital IC gates are classified not only by their logic operation, but also the specific logic-circuit family to which they belong. Each logic family has its own basic electronic circuit upon which more complex digital circuits and functions are developed.
The communications laboratory helps the students to understand the basic principles of communication systems by practical module systems. The experiments are designed in such a way that the theoretical concepts introduced in lectures are re-discussed and implemented a practically. The experiments deal with the analog communication basics such as amplitude modulation, frequency modulation, pulse amplitude modulation, pulse code modulation, signal to noise ratio, and signaling techniques: PSK, FSK, DPSK, QPSK, and MSK.
