    • Design Concepts for Power Distribution Equipment Serving Non-Linear Loads 
      Massey, G. W. (Energy Systems Laboratory (http://esl.tamu.edu), 1995-04)
      This paper explores the effects of power system harmonics induced by non-sinusoidal loads on electrical distribution equipment. The first portion examines the harmonic phenomenon to more fully understand harmonic current ...
    • Electrical Equipment Replacement: Energy Efficiency versus System Compatibility 
      Massey, G. W. (Energy Systems Laboratory (http://esl.tamu.edu); Texas A&M University (http://www.tamu.edu), 2005)
      Electrical equipment components are replaced every day because of failure, obsolescence, or upgrade. Because of technological gains, replacement components are typically more energy efficient than older equipment. Life ...
    • Guidelines for Power Factor Improvement Projects 
      Massey, G. W. (Energy Systems Laboratory (http://esl.tamu.edu), 1999-05)
      Power factor is an indication of electrical system efficiency. Low power factor, or low system efficiency, may be due to one or more causes, including lightly loaded transformers, oversized electric motors, and harmonic-generating ...
    • Relaying and Controls for Generator Applications 
      Massey, G. W. (Energy Systems Laboratory (http://esl.tamu.edu), 2000-04)
      In today's competitive marketplace, many electrical energy consumers are encouraged to enter into interruptible or cogeneration contracts by their electrical utility. Interruptible contracts provide year-round cost savings ...
    • Variable Frequency Motor Drives: Harmonics, Power Factor, and Energy Efficiency 
      Massey, G. W. (Energy Systems Laboratory (http://esl.tamu.edu), 1997-04)
      Variable frequency motor drives (VFD's) have been on the market for many years. Early versions were unreliable and prone to failure. Relatively recent developments in Pulse-Width Modulated (PWM) waveform technology have ...
