ELECTRICAL ENGINEERING LABORATORY.

The Scott Laboratory of Electrical Engineering.—This laboratory was
initially equipped and endowed by Mrs. Frances Branch Scott, of Richmond,
Va., as a memorial to her late son, an alumnus of this university.
During the year 1910 the equipment was substantially increased through
the generosity of the Hon. Charles R. Crane, of Chicago, Ill., a friend of
the university. During 1912, still further substantial additions were made,
consisting of measuring instruments, auxiliary control apparatus, and more
particularly a steam-turbine driven three-phase alternating current generator
with exciter and control switchboard.

In addition to full sets of electric meters with the appliances for testing
and calibrating them, galvanometers of the best modern types, standard
cells and resistances, standard condensers, and other pieces of apparatus for
minor tests, this laboratory contains numerous pieces of the very best
construction. Such are the Wolff Potentiometer, the Siemens and Halske
Thomson Double Bridge, the Koepsel Permeameter, the Duddell Double
Projection Oscillograph, the Station Photometer with Lummer-Brodhun
screen, the Carey-Foster Bridge and others. For the work in machine-testing

there are a number of direct current generators and motors, series,
shunt and compound, an interpole motor, a double current generator, a
two-phase alternator, a General Electric experimental test set for alternating
current, comprising a generator furnishing single, two, three, six
or twelve-phase current, and, in addition, offering three types of induction
motors with all necessary starting and controlling devices, a single-phase
repulsion motor, a two-phase induction motor, two three-phase induction
motors, several pairs of constant voltage transformers, a constant current
transformer, frequency meters, power factor indicator, synchronism indicator,
ground detector and the auxiliary apparatus used in testing these
machines. The laboratory has been arranged with a system of universal
plug and receptacle-connections to facilitate the setting up of all experimental
combinations.
