    Cable engineers have recognized for many years that losses which occur in the steel pipe of pipe cable systems appreciably increase ac resistance and greatly reduce possible ampacity of such systems. Nonmagnetic pipes did not offer a practical solution to the problem since available materials contributed essentially the same degree of loss to the system as steel pipes. Hence, from time to time, en... View full abstract»

    The application of dimensional analysis to measurements made on cold rolled electrical steels yields empirical equations relating ac core losses to hysteresis losses and other factors. As frequency increases from low values, three different patterns of loss variation occur because of increasing skin effect. Loss measurements indicate that samples with lower hysteresis losses and thinner gauges hav... View full abstract»

    A procedure is given which utilizes the digital computer to solve eddy current loss and hysteresis loss problems. The relationship between flux density and magnetic intensity is taken from the actual magnetization curve and major hysteresis loop, thus eliminating the approximations employed in most previous investigations. The nonlinear partial differential equations are replaced by finite differe... View full abstract»
