3a2 Chapter 8 Objective 4 - Detailed Analysis & Overview
Describe water, air & hydrogen cooling systems for large generators. Describe the stator & rotor designs, operation & applications for salient pole & cylindrical rotor alternators. Explain parallel operation of alternators & state the requirements for synchronisation describing both automatic and manual. Explain the principles and applications of power transformation. Perform transformer calculations. Define the following terms & explain their relationships in an A.C. circuit: capacitance, inductance, reactance, impedance, power ... Explain operating care & considerations that must be given to the various heat transfer sections of the boiler.
Describe the construction & operation of AC generators & motors. Interpret the information on a motor nameplate. Describe the function & operation of fuses & circuit breakers. Perform basic calculations relating to power factor & power factor correction. This lesson follows the text of Fundamentals of Electric Circuits, Alexander & Sadiku, McGraw Hill, 6th Edition. Describe the construction & operation of DC generators & motors.
