The accessory apparatus for the production of electric power, and its transmission and distribution to the consumer is the basis of a seminar type course. Each student investigates an assigned topic in some detail and discusses his findings for the information of the class. Prime movers, generator excitation and voltage regulation, feeder voltage regulation, station wiring layouts, switchboards and switching gear, reactors, relays and relay systems, line disturbances and line protection, plant economics and energy rates, industrial motor application and control are topics treated. _Text: “Standard Handbook for Electrical Engineers” (Sixth Edition)._ EE 42 Electric Transmission Circuits. Prerequisites, EE 31, EE 32. Aspects of electric power transmission which are subject to analytical attack are treated by lecture and computation methods. The topics included are: Calculation of short lines, low voltage distribution, conductor materials, spacing, corona effect, economic voltage and frequency, hyperbolic functions and the calculation of line constants, calculation of long lines by graphical, approximate and rigorous methods, comparison of methods, synchronous machines for power factor and voltage control, effect of transformers included in circuit regulation. _Text: Woodruff, “Electric Power Transmission and Distribution”; Everitt, “Communication Engineering”._ EE 43 Electric Machinery. Prerequisite EE 33. A continuation of Electric Machinery EE 33. EE 45 Electrical Measurements. Prerequisites, EE 31, EE 32. This is mainly a laboratory course illustrating some of the more advanced problems in electric circuits. In the associated classroom work the principles underlying the laboratory problems are discussed and the quantitative relations emphasized. The projects considered fall under the general heading of Measurement Circuits: Oscillograph study of direct and alternating transients. Alternating Bridges. Non-sinusoidal wave analysis. Balance methods of current measurements. Phase sequence indicators and meters. Problems of power measurement in polyphase circuits requiring voltage and current transformers. _Text: Nims, “Advanced Circuits Measurements Manual”._ EE 46 Electron Tube Circuits. Prerequisites, EE 35, EE 45. A continuation of EE 45, dealing principally with the following topics: Direct measurements of Tube Constants. Essentials of Amplifier Circuits of all types. Oscillator and Inverter Circuits. Rectifier and Relay Circuits. _Texts: Everitt, “Communication Engineering”; Nims, “Advanced Circuits Measurements Manual”._ EE 47 (EE 47-1, 47-2) Electrical Design. Prerequisites, EE 22, EE 33.
