Digital Computation of Short-Circuit Bus Stresses

A digital computer program has been developed for the purpose of checking the adequacy of generator and substation bus designs in withstanding mechanical stresses due to short circuits. Experience with the program to date shows that the computer carries out the required calculations in about 1/100 of the time needed by a trained engineer and provides a reduction in calculating cost of four to one. It is expected that the computer program will contribute to better engineered and more economical station design by making comprehensive bus stress analyses easier and less time consuming.
