Abstract
  • 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 eliminates the use of ground profile charts and sag templates. An integral part of this thesis is the determination of conductor sag and tension from the catenary equation. These data can be obtained from the computer program as a function of support spacing for any desired conductor input data. The complete program for tower location consists of several routines logically worked together to obtain the final result. These separate routines are: 1) The estimation of the initial span length based upon conductor data and desired ground clearance; 2) The determination of conductor end tensions including the effect of unequal support elevations; 3) The determination of the maximum sag relative to the two support points; 4) The relationship of ground profile to conductor profile is calculated to determine the magnitude and point of minimum ground clearance. Linear interpolation is used between data points. Several ground profile were tested. The results and a discussion of them are included in this thesis.
