  • Surge measurement errors of coaxial cables

    Publication Year: 1958, Page(s): 288
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (942 KB)

    NEARLY ALL surge or impulse voltage measurements involve the use of a cathode ray oscillograph (CRO) and measuring cable. All cables have a certain amount of attenuation and their surge impedance is never the same for all frequencies as indicated in several studies. In low-voltage impulse work (where very short cables can be used) such factors may be negligible under certain conditions, but for me... View full abstract»

  • Overcurrent protection in shipboard electrical systems

    Publication Year: 1958, Page(s): 293
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (297 KB)

    AS SHIPBOARD POWER DEMANDS have increased, it has been necessary to install more and larger generators aboard ship. It has been found that the most reliable and flexible system can be attained by arranging the bus ties in such a manner that they form a closed loop if all bus tie circuit breakers were closed. This arrangement can result in potential fault currents well over the maximum interrupting... View full abstract»

  • Precise measurement and the race for technological supremacy

    Publication Year: 1958, Page(s):294 - 296
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (777 KB)

    Technological progress can be reflected, fundamentally, by a country's level of competence in measurement techniques. The USSR's progress in this field is a challenge that, if ignored, could be instrumental in undermining world freeenterprise economy status. Thus, in the race for technological supremacy, the role of the U. S. National Bureau of Standards is vital. View full abstract»

  • The insulator contamination problem

    Publication Year: 1958, Page(s): 297
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1409 KB)

    POWER COMPANIES operating in areas subjected to air-borne contamination have, for many years, been faced with a difficult operating problem. Maintenance of satisfactory operation has required that insulators be cleaned periodically by hand wiping or periodic washing (energized or de-energized). Expensive overinsulation is frequently employed to alleviate partially the effects of surface contaminat... View full abstract»

    A DEFINITE TREND has been indicated toward higher subtransmission voltages to meet increasing load demands in certain metropolitan areas. High-voltage metal-enclosed isolated-phase bus structures offer a practical and economical solution to the bus and switching needs at these higher voltages and have many advantages such as simplification of arrangement, greater flexibility, and greater safety.

    The electric utility industry for a number of years has been investigating the problem of overvoltages caused by switching surges. Valuable and necessary to these investigations are firsthand reports from operating utilities. An experience of the Pennsylvania Power & Light Co., involving damage which occurred during switching on a 220-kv system, is described. View full abstract»

    THE MAGNETIC AIR CIRCUIT BREAKER, during the past two decades, has become a most effective and widely used circuit-interrupting device. The need for increased ratings in magnetic air circuit breakers has required critical studies of and improvements in the various factors involved in the interrupting process in these devices. One important factor, the magnetic field, has been improved in a number ... View full abstract»

    The era of high-speed nuclear propelled aircraft and missiles demands electronic equipment that can withstand intense nuclear radiation as well as much higher ambient temperatures than the 125 C required of equipment in current use. Major technological advances must be made in design and manufacture to realize these goals. View full abstract»

    WHEN, after only a brief stay in India, I write about Indian engineering education, it must be recognized that I do this only to address fellow engineers who have not had even that experience. Perhaps the brevity of my Indian experience will even help me to write in terms of the interest of the audience whom I address—I can so well remember what would have been new to me only two years ago....

    “Membership in the AIEE is a very important facet of my professional life. Being an electrical engineer engaged in the electronics field generally, and in the communications area specifically, and even more specifically the mobile communications field, it would be very easy to be interested solely in organizations that are directed at the immediate area of interest. However, the AIEE, becau... View full abstract»
