Electric Power Distribution System For Industrial Plants



The electric power distribution system plays an important role in the efficient operation of a modern industrial plant. Such a system includes high voltage circuit breakers, switchgear, transformers, motor control centers, electric motors, variable speed drives, etc. A trouble-free electrical system is essential for interruption-free plant operations. This course will cover all aspects of power distribution, including system planning, equipment selection, and application, system grounding, protection and conformity with electrical code requirements, etc. Participants will work under instructor guidance to develop a power distribution system single line diagram for a typical industrial plant.

Course Objectives:

At the end of this course, the participants will be able to:

  • Plan their system and select equipment for it.
  • Benefit from a clear understanding of all aspects of the power distribution system
  • Apply the Electrical Code to their projects
  • Deal with the important issues such as load estimating, voltage selection, shortage circuit studies, and power protection
  • Make their distribution system more efficient by applying your new knowledge of the power distribution system and equipment
