Terminals of these transformers are accessible to connect single-phase, autotransformer, three-phase as star, delta ……etc. connections for laboratory exercises. The laboratory also has numbers of DC motors and generators, all common arrangements such as series, parallel and compound machines are readily available at connecting plate of each machine. Synchronous machines are also provided to examine the behavior of the machines with different type of loads. Induction motors wildly used as slip ring and squirrel cage are also provided for studying the characteristic of the motors with and without loads. The laboratory also has frequency drive training unit including small three-phase induction motor and variable mechanical load to study the characteristics of the inverter. Feedback control system are also available, contains servo motors, servo motor controller and tacho-generator. Variable ac and dc electrical sources are supplied to the laboratory to facilitate the practical experiments. Many instruments are available to measure speed, torque, harmonics, load power, power factor, voltage and current. All this make electrical machines and power lab quit suitable for education and can be adopted for use in some research work.
6. Power System Lab
The objective of this laboratory is to allow integration and application of real-time monitoring, advanced sensing, communications, dynamic flow of both energy and information to accommodate existing and new forms of supply, delivery and use in a secure, reliable and efficient electric power system from generation source to end-user. Besides the knowledge of power systems, this lab supports education in several power system related areas such as communications, controls, electronics, instrumentation, computers and IT. This multidisciplinary and integrative nature facilitate the learning process and develop experiments with physical integrated solutions that allow future smart grid designers and operators to gain knowledge at different levels as revealed in Bloom's Taxonomy.
