About this exam
This is a 2013 final exam paper for electrical-engineering-lab-iv at aau (electrical-computer-engineering). This is the final examination for the Electrical Engineering Lab IV course at Addis Ababa Institute of Technology (AAiT), conducted in June 2013. The exam focuses on practical laboratory procedures, circuit analysis, and instrumentation for electrical machines. **Key Topics Covered:** Single-phase transformer testing (resistance, open circuit, short circuit, and load tests), three-phase transformer short circuit testing, identification of winding segments in three-phase induction motors, parallel operation of shunt DC generators, voltage drop causes in DC generators, and synchronous generator prime mover operation. **Exam Structure & Format:** The exam consists of four main practical and analytical questions requiring circuit diagrams, procedural explanations, and calculations based on provided instrument data (wattmeter readings). The total time allowed is 2 hours and 30 minutes.
