In this paper the characteristics of multi-conductor transmission
lines have been investigated for a variety of termination conditions
by using the differential equations and matrix methods.
Equations showing the characteristics of traveling waves along loss-less
multi-conductor systems are derived.
Line parameters were evaluated by experiments and by calculations.
The results...
The utilization of extra-high-voltage underground power cables
over distances greater than 100 miles presents serious problems relative
to the voltage and current limits of such cables. These problems
are directly associated with the fixed amount of capacitance inherent
in long cable lines. As a result, large charging currents are
characteristic...
The Cascadia Subduction Zone has recently been identified as a source for an impending great earthquake. The potential of a large earthquake has created widespread interest into the resiliency of lifelines within the potentially affected areas. One critical lifeline is the electrical distribution and transmission systems which relies on legacy...
A method of locating electric transmission line towers using
ground survey data in a digital computer program is presented in this
thesis. The towers are located for maximum spacing subject to the
constraints of available tower heights, forbidden ground areas, minimum
ground clearance, and specified conductor tensions. The digital
method...
This thesis presents two new approaches for the broadband, time-domain modeling of lossy transmission lines. Each approach is based on an alternative derivation of delay extraction in order to separate the line's linear phase from its
attenuation and dispersion. Augmentation networks represent the derived attenuation networks as rational function approximations....
The following discussion is confined mostly to

in 1870 and due to Tesla (1888), of the fact that two,...
