Estimate Electricity Loss from Transmission Line

Given the geometric architecture of a transmission pylon, estimate the electricity loss along the transmission line.

This program was originally written in Fortran in 1989 by David R. Brown and the American Public Power Association.

The following sources provided data on the electrical properties of different conductors:

  • AL/ACSR data: Aluminum Electrical Conductor Handbook, 1982.
  • Alumoweld data: Copperweld Steel Company, Southern Division, Fayetteville, TN.
  • Steel data: Mechanical Data from ASTM Standards, ASTM Standard A475.
  • CU data: Westinghouse T&D Reference, 1964, ABB Power Systems Inc.
