    A method has been developed to predict the probability of a double circuit outage on double circuit lines. Traveling wave techniques are used to account for nonlinearities such as corona, attenuation, and phase conductor flashover as its time iterative approach enables alteration of design parameters at each time increment. A geometrical model technique, involving comparison of lightning voltages ... View full abstract»

    A high-frequency noise voltage in a faulty transmission line generated by arcing fault is described. Many artificial arcing fault tests were conducted to clarify the features of this noise voltage, and field investigations were conducted to record the noise voltage generated by actual lightning faults. The noise voltage varies according to the value of fault current, types of fault, and time inter... View full abstract»

    The design and testing of high-voltage shunt reactors is discussed. The advantages of a gapped-core construction employing radial laminated limb sections with a relatively small number of air gaps, resulting in a simple mechanical construction, are described. A comparison is made between testing methods for transformers and reactors, special attention being paid to test power, loss measurement, me... View full abstract»

    Single suspension insulator units of several types as well as multi-unit strings were studied in a large refrigerated chamber. Rime ice of various densities was deposited on these insulators. The increase of leakage currents, the reduction of flashover voltages, and the alteration of voltage distributions along insulator strings caused by the presence of the ice were measured. The effects of vario... View full abstract»

    The switching surge insulation level of steel tower and wood pole transmission lines operating at system voltage levels of 115 through 500 kV are compared with the switching surge magnitudes that can occur on these systems. High-side and low-side switching with and without surge suppression resistors is considered. The results indicate that at 345 kV and above surge suppression resistors should be...

    A unified method of designing electrical machines is presented, utilizing the capabilities of modern, high-speed digital computers. The objective is to meet all performance requirements at minimum cost. The general approach is described by means of two examples, a program for design of power transformers and a program for design of hydroelectric generators. View full abstract»

    Self-excitation is proved to be a simple, reliable, and theoretically economical method for increasing the range of stable operation in a synchronous generator with particular reference to large turbine generators. When the excitation is realized following some general criteria derived in this paper, much greater stability is achieved than with conventional systems. This liberates the design of th...

    An all-digital simulation of an induction machine and its associated control system is described. The simulation is suitable for analyzing operation either from a constant frequency, constant voltage supply, or analyzing a complete control loop with a variable frequency power source. The computer program which is described calculates both the transient and steady-state performance of the machine f... View full abstract»

    The Piecewise Method of solution, better known as Diakoptics, is a procedure for solving large-scale system problems by tearing or decomposing. The problems to be analyzed seem to grow at a very rapid pace. Neither the increased computer speeds nor the computer core storages seem to keep up with the size and complexity of the problems to be solved. Diakoptics appears to be a good tool with which t...

    The recently proposed normal mode theory of current flow in straight, long conductors is applied to nonmagnetic, isolated, rectangular bars of various side ratios. Sufficient modal parameters have been computed to permit families of conductor resistance ratio and inductance variation curves to be given. These curves may be used to estimate the alternating current parameters of nearly any rectangul... View full abstract»
