ELECTRICAL POWER DISTRIBUTION SYSTEM FOR INDUSTRIAL PLANT
Deskripsi
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
To
provide practical understanding of a power distribution system and its
protection in an industrial plant.
