Cable Design for Protective & Metering Circuits in Substation Control Applications

Cable selection plays an important role in both the reliability, and longevity of a modern substation. This webinar presents various technologies for substation cabling for control, metering, and protection circuits. Presenter Peter Cox will also compare the benefits and weaknesses of each alternative, and the role of control cable in substation life.

Overview

In this presentation, you will receive an overview of switchyard components utilized in substations and various control elements of each component, as well as a comparison of the polymeric and shielding technologies of the cables available. You will also learn the selection criteria a designer or specifier might consider in developing specifications that meet or exceed the useful operating life of the substation. Discussion will also include insulation, jacketing, and shielding options, as well as shield termination techniques.

The webinar covers the cost, benefits, and risks associated with each common insulation material, as well as shield applications and terminations of the various types of shielding that could be specified. Additionally, the strengths and weaknesses of different cable jacket materials and their associated standards (UL, ICEA, IEEE) will be discussed.

The presentation will also include cabling requirements for protective and metering circuits, plus details of other low voltage control requirements that may be found in substation applications, and an introduction to networking products designed for substation systems.

Key Take-Aways

  • Learn the advantages and disadvantages of various cable designs to implement in engineering substation layouts
  • Understand the performance of helical vs longitudinal copper shielding and the role of a ground wire
  • Learn how to identify cabling that will properly handle fault currents, and last for the life of the substation without failure, while providing effective protection to connected equipment
  • Have an overview of the basic electrical schematic flow, how the automation assists with data collection and sharing, and how components interact together to create a smart system
