OVERHEAD T&D SOLUTIONS RateKit™ Thermal Rating Toolkit Software General Description Fast and accurate answers for day-to-day rating decisions at your fingertips! RateKit™ Thermal Rating Toolkit software is the first fully integrated transmission line rating program that combines steady state and transient rating programs with calculation modules for loss of strength and high temperature sag calculations; it is the most sophisticated implementation of IEEE 738 and CIGRE TB-207 standards for rating overhead transmission lines. The enhancements embedded in the software make it the most powerful commercially-available thermal rating tool in the market. It is equally useful to T&D engineers, planners, dispatchers, and operations supervisors when answering critical questions such as: What is the temperature increase during a 10-minute emergency? What was the loss of strength resulting from a recent 2-hour emergency? How much will the temperature of the conductor change if the wind drops to zero? What is the sag error introduced by manufacturing variations in conductor properties? Steady state rating conductor temperature The software is capable of utilizing both the IEEE Standard 738 thermal rating method and the CIGRE TB-207 method. Capabilities include steady-state rating and temperature calculations, sag calculations, radial temperature gradients, annealing calculations, transient rating and temperature calculations, as well as “Batch Mode” calculations and plots which enable sophisticated simulation and analysis abilities. The user-friendly interface avoids any possible confusion in the calculations and methods that are available in this program. Design data may be chosen in either SI or US units, while the choice of calculation type can be made independently of the units in the entry of design data. Most U.S. conductor types, as well as an extensive set of standard European conductors (German, French, and British) are selectable by their code names without the need for separate inputs of conductor properties. The software includes a unique sag/tension program that calculates the sags and sag changes in any span of a ruling span line section. Moreover, it offers user-variable input of the “knee-point temperature” of ACSR conductors, permitting various assumptions to be made about aluminum compression. Calculations can be made either in U.S. conventional units or SI units. FOR MORE INFORMATION A free demo is available for download.
