A-C power system at the fairless works

THE Fairless Works of the United States Steel Corporation, located on a bend in the Delaware River near Morrisville, Pa., was designed as a completely integrated plant, capable of processing raw materials into finished steel products, ready for industrial use. Seldom in the history of steel mills have engineers had the opportunity to design so complete an undertaking in its entirety, and thereby to take advantage of past experience from both technical and economic standpoints. This paper deals with the electric power system which supplies the loads of the various mill areas. Fig. 1 is a scale drawing which shows the high-voltage substations and transmission lines of the Fairless Works. The technical and economic considerations used as a basis for the design and operation of this system will be discussed.
