COURSE OBJECTIVES A. What are we going to do? One of the main purposes of this lab is to familiarize the student with the main areas of study of conventional electric energy conversion: 1) Power Measurement & Instrumentation 2) Transformers 3) DC Motors & Generators 4) Induction Machines 5) Synchronous Machines B. How are we going to do it? In order to study these areas, the course will consist of the following experiments: 1) Alternating Current. 2) Three Phase Circuits 3) Magnetic Circuits and Transformers 4) Synchronous Machines 5) AC Induction Motors 6) DC Machines These experiments will enable the student: 1) To gain an understanding of the characteristics of the principles governing electric energy conversion devices, 2) To understand the validity of the most elementary models of these devices, and 3) To gain a working knowledge of power instrumentation and the limitations of each instrument, among other things. C. What else? Another objective of this lab is to help the future professional, in our case the engineer, to develop well rounded laboratory skills. These skills will enable this professional to do the following: 1) To follow instructions. 2) To translate a schematic diagram into a working piece of hardware. 3) To use appropriately instrumentation on machines. 4) To take data systematically in table form from an experiment. 5) To debug a faulty circuit set up. 6) To report IN A PROFESSIONAL MANNER the results of the experiment, with all the supporting evidence such as the purpose, theory, procedure & data, analysis of data, and conclusions. The first five skills will be learned in the laboratory environment, and the sixth one will be mastered outside the classroom following the guidelines given in this manual and during class. EEL 4201L Basic Electric Energy Conversion Lab rev. 8/2009 3 II. SAFETY RULES AND REGULATIONS The electrical power laboratory constitutes a hazardous environment; it has the potential to seriously injure and even kill! Theodore Bernstein has made some research on the area of electrocution. Some facts taken from his 1983 paper are the following: Threshold of perception for a finger-tapping contact at 60 Hz is about 0.2 mA. Let-go Current (60 Hz) for women = 6 mA, for men = 9 mA. Asphyxia can be caused by 60 Hz currents of 40-60 mA across the chest. Ventricular Fibrillation can be caused by currents of 150 mA for 1 sec. These current levels are in the mA range; however, in this lab, you will handle excitation currents of up to 860 mA (!) and armature currents of up to 6 or 7 A!...
