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 steamturbine-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 directcurrent
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.
