Training Course: Electric Power Distribution System For Industrial Plants

Introduction 

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 an interruption-free plant operation. 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.

Objectives

Upon Completion of the Course, Participants will be able to:

• Plan your system and select equipment for it.

• Benefit from a clear understanding of all aspects of power distribution system

• Apply the Electrical Code to your projects

• Deal with the important issues such as load estimating, voltage selection, shortage circuit studies and power protection

• make your distribution system more efficient by applying your new knowledge of the power distribution system and equipment

Target Audience 

Electrical power distribution engineers, electrical power system engineers, plant managers, plant engineers from all types of industries particularly chemical and petroleum, large institutional power distribution engineers, consulting engineers and other engineers as well as technical personnel involved in the design, engineering, operation and maintenance of power distribution system in industrial plants.
