The designing of electrical machinery is fully
as essential to the thorough understanding of power
equipment and apparatus, as is the taking of a laboratory
testing course. One learns the relationship
of the different parts, the methods of computing
their dimensions, and the predetermination of outputs,
efficiencies, etc. and thus...
Samples of insulating materials used in the construction
of electrical machinery and apparatus are
tested for dielectric strength before such are accepted
for use. This is done by applying to the sample a
high voltage until it is pierced through by the electric
spark. This is a parallel case to...
By reason of the fact that a thesis along the
line of one's course or about some subject with which he
is supposed to be familiar is required of every Senior
electrical by the electrical department before his graduation, the following description of the design and construction of a 10...
In view of the fact that the college authorities have
purchased a set of wireless apparatus, it was thought best
to design and construct a transformer of suitable size for
transforming the power to be used by this set of instruments.
The power required for such a set is approximately...
The data used in the design of this hydro-electric
generating station was furnished by Hon. Walter M. Pierce
from a survey conducted by T. R. Barry C. E. in the service
of the Grande Ronde Water Co. during the summer of
1906.
In the preparation of this thesis there were...
The induction motor in its electromagnetic features
is essentially a transformer, while in its general behavior
it is analogous to the continuous-current shunt wound
motor. In a transformer the primary and secondary members
are both stationary and electrical energy is transformed
from one pressure to another by the ratio of...
During the last five years the demand for electrical
energy in the state of Oregon,and throughout the entire
country,has increased to such an extent that electrical
generating stations have become an important factor in the
economic development of the common wealth.
Uonsidering the great need for cheap power, which
is...
"There are at present four common methods of con
verting the alternating current into direct current.
These are in order of use, the motor generator set,
the rotary converter, mercury vapor rectifier and the
Murphy rectifier. A short description of these and
connections for the last two will be given."--p.2
