"Before a company which manufactures electrical
machines allow them to leave the factory, each must
undergo certain tests to make sure that there are no
faults of design or workmanship and also ofttimes that they meet the specifications of the buyer. Four important
tests are made, e.g. (1) no load...
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...
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...
This thesis comprises a series of tests run on a compound direct current generator and an induction motor; separately and combined as a set, with sheets of data; characteristic and efficiency curves and deduction drawn therefrom relative to the two machines.
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 marked movement of utilizing Oregon's water power
in the service of generating electric current, has been promoted
by the economics in transmission of electricity to distances
both great and small; by the harnessing of industrial
implements to electric power; and by the advancement and extension
of interurban railways.
It...
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...
