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 applicances 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 Seimens 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.
