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.
Substantial additions of machines, measuring instruments, control apparatus,
and auxiliaries are being made regularly in order to keep the equipment
in the best order for laboratory work.
In addition to a supply from the University Power Plant the laboratory
is furnished from the Virginia Public Service Company through a synchronous
motor driving an alternator and three-wire direct current generator, with two
exciters, all on a common shaft. A complete three-panel switchboard for the
control of this set is equipped with full sets of instruments and controls including
a voltage regulator for the alternating current generator. Universal
plug and receptacle-connections facilitate the setting up of all experimental
combinations.
For the machine testing there are available several direct-current motor generator
sets with automatic push-button start and stop control complete, numerous
direct current motors and generators, series, shunt and compound; high-voltage
direct current generator set; steam-turbine-driven three-phase alternator with exciter
and control switchboard; two experimental test sets for alternating current
single or polyphase generator operation with modern switchboard control
panel and driving motor with automatic start, stop, and reverse equipment; single-phase
induction motor; single-phase repulsion-induction motor; two- and three-phase
induction motors; three-phase induction-motor set for concatenation tests;
induction generator; double-current generator; several pairs of constant potential
transformers; constant-current transformer; polyphase transformer; mercury arc
rectifier set; frequency changer; arc welding set; Fynn-Weichsel synchronous-induction
motor; a number of different types of fractional horse-power motors both
D. C. and A. C.; Prony brakes for all motors; variable resistances; variable
inductances and capacities; current and potential transformers; recording instruments;
meters for measuring frequency, power factor and indicators of synchronism
and grounded circuits. A complete three-element oscillograph set with all accessories
is available. Two telephone central-office ringer and signal sets, representative
pieces of modern telephone quipment, and a 100-watt radio broadcast
transmitter are installed. A complete artificial transmission line with oscillator,
communication tests.
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 Station photometer with Lummer-Brodhun
screen, Macbeth illuminometer, the Carey-Foster bridge and others.
