    A new load flow program has been developed which employs the node-impedance matrix of a system. A special input routine was developed that allows the line data to be in any order desired. The program has the capacity to control generator voltages within a specified var (reactive volt-ampere) range, and also to incorporate off-nominal autotransformers. In every system studied using this program, th... View full abstract»

    Network relationships have been rigorously derived on a combined open-path and closed-path basis particularly suitable for networks containing autotransformers and phase shifters. The network relations also correctly yield the real and the reactive losses of the network. Matrix and nonmatrix methods for obtaining all the terms in the derived relationlships are also presented.

    The force on a current-carrying wire in a magnetic field and the torque developed by an armature are special cases of the principle that a current-carrying coil, when linked with a magnetic field produced by a separate agency, tends to assume a position such that its electrokinetic energy due to that linkage has maximum value. The elastic band properties of lines of force and the effect of Amperia... View full abstract»

    The magnitude of predischarge currents of gaps under impulse conditions have been determined. For gaps formed by two parallel pipes the magnitude is found to be approximately proportional to the length and to the spacing. These currents, which must be drawn through the impedance of the line, produce drops at 2 or 3¿sec (microseconds) that may be equal to or greater than the gap voltage. Adaptatio...

    Though commutation is one of the important factors in the designing of d-c machines, the existing method of designing the commutation is very crude. It is generally admitted that the best method of checking the quality of commutation experimentally is to plot no-spark zone diagrams and examine them. Therefore, if no-spark zones could be determined through calculation, it would be a great step forw... View full abstract»

    Experimental comparisons of radio influence (RI) fields from long and short lines were made on a section of a 70-mile 345-kv transmission line. The results of these tests show that for line RI generation the long line RI level can be obtained from short test line data. Tests with a single RI source on the line are also described.
