Rating of Electric Power Cables in Unfavorable Thermal Environment is the first text to provide you with the computational tools and techniques needed to successfully design and install power cables in areas affected by such factors as outside heat sources, ground moisture, or impediments to heat dissipation. After thoroughly reviewing standard rating models, the author discusses several new techniques designed to improve cable ampacity, as well as new computational techniques for analysis of cyclic loads. To facilitate computational tasks he utilizes six representational model cables throughout the book, including transmission-class, high-voltage, distribution, and bundled types. End-of-chapter summaries, liberal numerical examples, and practical, real world applications make this text a valuable resource for making better design and operation decisions.

From the Jacket

A cutting-edge resource on the ampacity calculations of power cables in diverse environments

The restructuring of the electric power industry has led to more heavily loaded transmission circuits than ever before. Consequently, cable-rating standards need to address diverse environmental conditions that can result in thermal overloads.

Rating of Electric Power Cables in Unfavorable Thermal Environment is the first text to provide energy professionals with the computational tools and techniques needed to successfully analyze the thermal behavior of power cables in areas affected by such factors as outside heat sources, ground moisture, or impediments to heat dissipation.

After a thorough review of standard rating models, the author discusses several new techniques designed to improve cable ampacity, as well as new computational techniques for analysis of cyclic loads. The author utilizes six representational model cables throughout the book to facilitate computational tasks, including transmission-class, high-voltage distribution, and bundled types.

Advanced topics include:

  • Continuous and time-dependent rating equations for underground and aerial cables
  • Cables crossing other heat sources or short sections with high soil thermal resistivity
  • Soil dry-out and transient rating calculations
  • The application of thermal backfill, including nonlinear optimization of backfill design and the probabilistic analysis of cable ampacity
  • Load variability and transient rating calculations
  • Rating issues for cables in air- and pipe-type cables with slow oil circulation

End-of-chapter summaries, liberal numerical examples, and practical, real-world applications make this text a valuable resource for energy professionals seeking to make better design and operation decisions.
