The 1200-volt railroad — A study of its value for interurban railways

[{u'author_order': 1, u'full_name': u'Charles E. Eveleth'}] Proceedings of the American Institute of Electrical Engineers, 1910

The various 1200-volt interurban railways have now been operating a sufficient length of time to prove that there are no material objections to the use of this voltage on passenger cars. The nature of such minor difficulties as have been experienced have been such that their correction has required only detail changes of design which have been readily made. The ...

Generally, high-temperature superconducting coated conductors (CC) are hard to be quenched by local and transient disturbances during normal operation because of the high temperature margin and high heat capacity of the conductor. However, the CCs still have possibilities of unexpected quenches originated by the appearance of local defects due to repeated mechanical stresses, and by temperature rise of the long ...

  • A C‐RAN Approach for 5G Applications

    5G networks are anticipated to obtain Shannon‐level and beyond throughput, and almost zero latency in future cellular networks. However, there are several challenges to solve if 5G is to outperform legacy mobile platforms; one of these is the design of the communication ‘haul.’ Traditionally, the backhaul segment connects the radio access network (RAN) to the rest of the network where the baseband processing takes place at the cell site. However, in this chapter, we will use the concept of ‘fronthaul access,’ which is recently gaining significant interest since it has the potential to support remote baseband processing based on adopting a cloud radio access network (C‐RAN) architecture that aims to mitigate (or coordinate) interference in operator‐deployed infrastructures; this eases significantly the requirements in interference‐aware transceivers. To do this, we provide a reference architecture which includes a network and protocol architecture incorporating a so‐called ‘cloud resource optimizer.’ The emergence of wireless fronthaul solutions widens the appeal of fronthaul for small‐cell deployments, because a fibre‐only solution – the technology typically used for fronthaul – is too expensive or just not available at many small‐cell sites. Moreover, we will also present the idea of virtual mobile small cells; these small cells are created on demand according to traffic demand.

  • Rotor Inspection

    This chapter talks about inspection of the rotor, mostly while removed from the stator. It aims to serve as a guide to learning the specific problems and failure mechanisms, and their identification that will make it possible to correctly assess intrinsic risks for a given design, and to notice explicit signs of deterioration, damage, and/or impending failure. In large machines, balance weights, bolts, nuts, and any other rotor attachments are subjected to intensive centrifugal forces. The chapter provides discussion about the condition of the windings, cleanliness, or the lack of it, that plays in the condition of the rotor. The end rings contain the radial displacement of the copper end windings and the supporting blocks. In two‐or four‐pole machines, one arrangement of the rotor‐mounted fans has the fan blades attached to fan rings or hubs shrunk onto the shaft.

  • Three-Phase Circuits

    This chapter shows that the genesis of three-phase lines and systems and provides information on how to make computations with these systems in the particularly important (and easy) case of balanced three-phase systems. Important advantage of three-phase systems is the fact that, differently from single-phase transmission, the instantaneous power delivered by three-phase generators and transferred to three-phase loads is constant. The three load impedances discussed were connected between the line wires, forming a triangle. The chapter describes the single-phase equivalent of the three-phase circuit and power in three-phase systems. It discusses the single-phase feeding from three-phase systems. Finally, the chapter ends with short biography of Tesla.

  • Fundamentals of Ground Grid Design

    The grounding system is an essential part of both high- and low-voltage electrical power networks. Design of a ground grid is part of the overall design of a substation. The ground rods are driven in and the ground grid constructed before the surface layer of gravel is poured and the above-ground portions of the substation constructed. The most important factor in terms of overcurrent phenomena is the sizing of the ground grid conductors. The conductors of a ground grid should be designed for a particular maximum fault current, X/R ratio, and clearing time. This chapter illustrates a design data for ground grid example from IEEE standard 80. This calculation is performed using improved and more uniform calculation procedures than those used in the referenced standard.

  • Coil Design and Temperature Calculations

    Magnetic actuators and sensors are often components of large systems, such as automobiles. The actuators and sensors must perform reliably in the system environment and interface properly with the system. To interface properly with system power supplies, the coils of the magnetic components must be properly designed. As part of the coil design, the temperatures developed by the coils and the components must be predicted. This chapter discusses the coil design and temperature calculations for magnetic actuators and sensors. The concepts discussed in the chapter are wire size determination for direct current (DC) currents, coil time constant and impedance, skin effects and proximity effects for alternating current (AC) currents, and finite-element computation of temperatures.

  • Rotor Winding Insulation Systems

    This chapter outlines where insulation is needed and the stresses that act on the insulation for the various rotor winding components such as windings, slip rings, retaining rings, end winding banding, etc. Rotor winding insulation is exposed to stresses that are different from those in the stator winding. Most types of rotors in motors and generators, except the SCI type, have both ground and turn insulation. Collector rings are also needed for wound induction rotor motor windings. The retaining ring insulation is inserted between the radial outer (or top) of the field coils and the retaining rings. A number of materials have been used for retaining ring insulation. More complicated designs for direct-cooled rotors for the largest generators utilize hollow sections of copper for the slot sections of the coils and partially for the copper under the retaining rings.
