Distribution Systems

Provided by: ToolingU

"Distribution Systems" describes power distribution systems and their components. Distribution systems are integral parts of motor control systems because they consist of all generators, transformers, wires, and other devices used to transport power from the source to end use. Generating stations house generators that are linked together in parallel circuits to create power. Transformers step up and step down voltage. Substations house transformers and provide a safe point to cut the power. Understanding the ways in which electricity is distributed and how to work safely with distribution systems is an essential part of working within motor controls. After taking this course, users will be able to describe how power enters a facility and is distributed to electrical equipment, as well as best practices for safely working with electrical power distribution systems.
