218 University College, Galway.
Electrical Engineering Laboratory.
This department occupies part of the ground· floor
and first floor of the new building.
The large laboratory and the battery room are on
the ground floor, and the lecture room and small
laboratory on the first floor.
IQ the large laboratory there are several modern
machines, including a 10 K.W. three-phase revolving
field alternator, driven by a variable speed continuous
current motor; a 5 B. H. P. three-phase asynchronous
motor; three single-phase oil-cooled transformers, 200
to 600 volts; a pair of 8 K. W. continuous current
machines with commutation poles, arranged for working
either shunt or compound; a 3 B.H.P. continuous
current series motor, with rever:;ing controller; and
one or two smaller shunt machines.
There are two large working benches fitted with bus
bars at different potentials, for testing instruments and
general apparatus.
The tables. the motors, and also the lecture-table
and small laboratory on the first floor, are supplied
from a large battery of 70-200 ampere hour Tudor
accumulators, through a double-pole distribution
Board. arranged so that any potential difference up
to 140 volts can be available at any point.
There is a valuable collection of instruments. both
standard and commercial types, which is added to
from time to time.
The lecture-room on the first floor has, at present,
seating for twenty-four students, but the floor space
will allow of considerable extension should this become
necessary. The lecture-table is in connexion
with the battery and machines helow. There is al90
a projection lantern.
The small laboratory is for advanced work. and the
more delicate apparatus is installed here.
