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...
The scope of this thesis consists primarily of
an exposition upon the merits of indirect and. semi-indirect
illumination. In deriving our conclusions, we
have considered two sources of information: firstly,
that of test data from a number of indirect and direct
installations, and. secondly, the opinion of men familiar
with...
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...
In any electrical system no part is stronger than the weakest link. It is very important that the insulation of the transmission line be kept intact at all times. For this reason any improvement in the design or manufacture of insulators would be desirable.
The object of this research was...
The question of whether to purchase power or to
maintain an isolated plant is one which frequently
confronts the engineer, and the problem is by no means
easy of solution, as there are a number of factors
which vary with individual cases and determine the
economy and desirability of the...
Following the installation of a street car
system, or for that matter, any other electric system,
using the ground return, or the rail return which comes
in contact with the ground, there is always more or
less trouble experienced by water or gas companies,
using metal pipe, due to the...
Throughout the year the regular design work of the
class room proved so profitable that it was thought that
there was no subject which could be selected for thesis
purposes of greater benefit,or which offered as great a
latitude in the working out of the various problems, than
the one...
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...
