ELECTRICAL ENGINEERING.

Engineering 2E. [Rodman].

The work of the Fall Term is devoted to the study of the Elements
of Electrical Engineering
as comprised in the fundamental
principles of electrical measurements and of electric and magnetic
circuits.

Especial attention is given to the fundamental laws of Ohm and
Kirchhoff with practical exemplifications in numerous assigned problems.
The latter part of the term's work is introductory to the
detailed study of direct current dynamo machinery.

The laboratory course paralleling the lectures is devoted to the
methods of using electrical measuring devices and to the more elementary
tests of the characteristics of electric and magnetic circuits.

The winter Term is devoted to a detailed study of the theory,
construction, characteristics and operation of Direct Current Generators
and Motors
and the accessory apparatus required for their
proper management and control. The latter part of the term's work
is concerned with the theory, construction and operation of Storage
Batteries
of approved modern types. Problem work illustrating the
methods of calculation involved in direct current circuits and practical
examples from standard engineering practice form an important
adjunct to the lectures.

The parallel laboratory course is concerned with the experimental
determination of the complete characteristics, the efficiency and
the temperature conditions which are manifested in the practical
operation of direct current dynamo machinery and storage batteries.

The Spring Term is given to the study of Periodic Currents.
A careful study is made of circuits and their characteristics when
resistance, inductance and capacity are present in all their possible
combinations. Extended problem work is required to facilitate the
treatment of simple and complex circuits. Free use is made of
vector and symbolic notation and graphical solutions, while especial
attention is given to the standard methods of nomenclature by
means of which otherwise confusing effects may be clearly elucidated.

The physical conceptions are kept always prominently in view
and the value of mathematics as a tool is emphasized. The latter
part of the course is devoted to a rapid survey of alternating current
machines and apparatus in order to familiarize the student
with general types and characteristics.

The laboratory is chiefly concerned with the more complicated
tests on direct current machines, only a few exercises being devoted


231

to the study of circuits carrying periodic currents. Lecture hours,
9-10, Thursday, Friday, Saturday; laboratory hours, 12-2, Monday,
Tuesday.

The Fall Term is spent in a detailed study of Alternating Current
Generators and Transformers
with their accessory measuring and
controlling devices. The theory, construction, regulation and operation
of single and polyphase generators are discussed, and the details
of standard types of transformers are carefully considered.

Graphical diagrams showing operating characteristics are
freely used as offering the most readily comprehensible treatment of
the complex relations existing in alternating current circuits.

Assigned problem work illustrating the theory and practice is
made use of to supplement the lectures.

The laboratory work gives practical demonstration of the characteristics
of alternating current apparatus and complete characteristic,
regulation and efficiency tests are made on non-inductive and
reactive loads for single, two and three phase arrangements of both
dynamo machines and transformers.

The Winter Term is a continuance of the study of Alternating
Current Phenomena,
especial attention being directed to the various
types of Alternating Current Motors, synchronous and induction,
both single and polyphase, with their theory, construction, operation
and auxiliary control apparatus. Extended problem work
forms an important adjunct to the lectures and recitations.

In the laboratory the theory is put to proof by means of tests
performed on motors of all types, operating under ordinary conditions.

Torque and efficiency runs are made, and the adaptability of
each special type of motor for various work is made prominent.

The Spring Term embraces work which is in part a résumé of
the entire course, being devoted to a general study of Generation,
Transmission and Distribution of Electrical Energy,
prime movers,
generating apparatus, switchboards and protective devices, high tension
long distance transmission lines, substations, and the economic
design and operation of modern electric power plants, and transmission
systems. Particular attention is paid to the problems concerned
in the design and construction of power plants and in the
choice of units.

The laboratory work is devoted to the completion of the more
complex tests on alternating machinery as units and as complete


232

systems. Lecture hours, 11-12, Thursday, Friday, Saturday; laboratory
hours, 9-11, Monday, Wednesday.

The Fall Term is given to the study of Electric Lighting and
Photometry.
The student is made familiar with the modern types
of illuminants and their characteristics. Photometry and photometric
standards are discussed, and some of the general problems confronting
the Illuminating Engineer are treated. Problem work illustrating
the computations necessary for the consideration of the
lighting expert are made an important part of the course.

The laboratory tests are devoted to detailed studies of incandescent
and are lamps as to their luminous effects, efficiency and
general characteristics.

During the Winter Term a study is made of Electric Traction
and Traction Apparatus,
including the various types of direct and
alternating current railway motors, controllers, brakes, rolling stock,
track, train performance and electric railway economics. A discussion
of the particular advantages of direct current, single phase
or polyphase, motor action is taken up and the best uses for each
system are outlined.

The laboratory is complementary to the course during the same
term which deals with alternating current motor testing.

The Spring Term hours for this course are given over to form
a part of the required Thesis time. Lecture hours, 12-1, Thursday,
Friday, Saturday; laboratory hours, 11-2, Wednesday.
