    Safety and reliability of electric distribution systems depend on many factors, including proper grounding. Correct functioning of ground fault relays depends on carefully designed busway housings and conduit connections. Busway housings are recommended as the preferred equipment grounding means because they achieve a low voltage drop value with little danger of electric shock. Eleven specific sug...

  • Drive Systems for Float Glass Installations

    Publication Year: 1969, Page(s):416 - 421
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (5043 KB)

    Implementation of the float glass process requires continuous control of the glass ribbon from the molten state through the solid state. The areas which present the greatest challenge to the drive manufacturer are the tin bath and the annealing lehr. Here the glass is changing state continuously, requiring the drive systems to provide precise speed, speed ratio, and position control. To provide th... View full abstract»

    Rapid growth of pipeline and refinery industries, especially where power systems are "weak" and equipment is fully automated, makes it frequently necessary to start large electric motor drives under adverse conditions. Voltage may sag, and motor torque available for acceleration goes down as voltage squared. Or the motor may have to start a fully loaded pump. Understanding these conditions is esse...

    Factual information is presented to show that rerate T-frame motors offer users substantially more value than motors of prior vintage. The gain is not alone a matter of size-weight reduction nor the obvious economic one of avoiding, in industrial ac motors, the inflationary price spiral that generally afflicts American manufactured products. Gains are also evident in: insulation life expectancy, b... View full abstract»
