ELECTRICAL ENGINEERING.
900. Elements of Electrical Engineering. [Rodman.]
9-10, Th. F. S.
Lectures treating fundamental principles of Electrical Engineering.
Free use of the calculus is made in this course. Basic ideas and fundamental
units are discussed; magnetic circuits and continuous electric currents
treated in detail; electromagnetism carefully studied. Special attention
is given to the physical conceptions involved and numerous assigned
problems exemplify and broaden the theoretical conceptions. The whole
course is introductory to the detailed study of electrical apparatus and
machines. (Fall.)
901. Direct Current Machines. [Rodman.]
9-10, Th. F. S.
Lectures on the theory, construction, characteristics, and operation
of Direct Current Generators and Motors and the accessory apparatus
required for the proper management and control of these machines. The
principles of testing such machines are carefully discussed. A brief treatment
of the theory, construction, and operation of Storage Batteries and
auxiliary devices concludes the term. Problems illustrating the methods
of calculation involved in continuous current circuits and practical examples
from standard engineering practice form an important part of the
work. (Winter.)
902. Periodic Currents. [Rodman.]
9-10, Th. F. S.
Lectures on electrostatic phenomena, variable currents, alternating
currents, and alternating current circuits both single and polyphase. A
careful study is made of circuits with periodic currents and their characteristics
when resistance, inductive reactance and capacity reactance are
present in their various combinations. Extensive problem work is required
to facilitate the treatment of simple and complex circuits. Free use is
made of vector and symbolic notations and of graphical solutions; while
standard nomenclature is carefully discussed. Special efforts are made
to keep the physical conceptions prominent while the value of mathematics
as a tool is emphasized. (Spring.)
903. Alternating Current Machinery. [Rodman.]
11-12, Th. F. S.
Lectures on the theory, construction, characteristics, and operation of
Alternating Current Generators, Synchronous Motors, Rotary Converters,
and Transformers. These machines are considered as units and as integral
parts of electrical systems. Graphical diagrams are made use of as offering
the most readily comprehensible treatment of the complex relations
existing in alternating current machinery. The principles of testing such
apparatus under various conditions of loading are discussed and assigned
problem work illustrates the theory and practice. (Fall.)
904. Alternating Current Machinery. [Rodman.]
11-12, Th. F. S.
This course is a continuation of 903. The lectures treat more particularly
Alternating Current Motors, induction, series and repulsion types,
with their characteristics and control apparatus. Methods of testing are
outlined and graphical methods of calculation and predetermination of
operating characteristics are discussed. Problems taken from engineering
practice serve to broaden and fix the theoretical deductions. (Winter.)
905. Electric Power Transmission. [Rodman.]
11-12, Th. F. S.
Lectures on systems of transmission and distribution, with a detailed
consideration of the electrical characteristics of transmission lines; the
electrical equipment of stations and sub-stations, including generating
apparatus, switchboards, control systems and protective devices; systems
of transformation and the economic considerations which influence the
design of the complete electrical system. (Spring.)
906. Illumination and Photometry. [Rodman.]
12-1, Th. F. S.
Lectures on light, its physical properties; illuminants and their characteristics;
shades and reflectors; photometry, standards and apparatus;
illumination calculations for point and surface sources; principles of interior,
exterior, decorative, and scenic illumination. Problem work illustrating
computations necessary for the consideration of the Illuminating
Engineer are assigned. (Fall.)
907. Electric Traction. [Rodman.]
12-1, Th. F. S.
Lectures on the various types of electric motors for traction purposes,
controllers and systems of control, brakes, rolling stock, track, train performance,
and electric railway economics. A discussion of the complete
electrification system for electric railways, including generating apparatus,
transmission, sub-stations and equipment, distribution, and utilization
of electrical energy for car propulsion. Problem work dealing with
the fundamental considerations necessary for the solution of traction problems
is required. After February first, three extra periods a week are
devoted to this course. (Winter.)
908. Electrical Systems. [Rodman.]
10-11, Th. F. S.
Lectures dealing with the fundamentals of electrical circuits and machines;
utilization of electricity as a motive power in industrial activities.
Followed by a more detailed discussion of the types of power stations and
structures utilized in electrical systems; railway construction and line
structures treated with relation to their layout and design; mechanical
characteristics of complete electrical systems. This course gives a general
survey of the electrical field more particularly for the students of Civil
Engineering. (Fall.)
950. Direct Current Laboratory. [Rodman and Instructor.]
3-5, T. Th.
This course supplements 900-1. The laboratory work is devoted to a
study of electrical instruments, their use and manipulation; simple electrical
circuits and study of direct current apparatus and its operation;
characteristics of generators and motors. (Winter.)
951. Direct Current Laboratory. [Rodman and Instructor.]
3-5, M. W.
This course supplements 950. It is concerned with some of the more
detailed and special tests of direct current apparatus and serves to broaden
the field presented in 950. (Winter.)
952. Direct Current Laboratory. [Rodman and Instructor.]
3-5, T. Th.
A continuation of 950-1. The work is devoted to those direct current
tests in which machines are grouped and with such tests as opposition
tests for efficiency, parallel running of generators and the complete electrical
power plant. (Spring.)
