Electrical Foundations Training Series

Contact Hours: 8

Course Description

The Electrical series of modules covers the fundamentals of electrical systems and components in an industrial facility. Subject areas within this series include Motor and Motor Control, Variable Frequency Drives, Circuit Protection, and Transformers.  This series consists of 16 modules. Each module is 30 minutes in length.

 

Motors and Motor Control

The electric motor is the workhorse of the modern industry. Its functions are almost unlimited. A thorough understanding of the function of the various components of a motor control center is desirable from both a maintenance and a troubleshooting standpoint. Properly maintained motors and motor control centers ensure a minimum of downtime for unscheduled repairs, increase productivity, and contribute to a safer working environment. The Motor and Motor Control subject area covers many aspects of these workhorses, including direct and alternating current configurations, protection, motor starters, and basic electrical and control circuitry.

 

Variable Frequency Drives

The use of variable frequency drives, or VFDs, allows exact speed control by controlling the voltage or the current of a motor. Understanding the fundamentals of VFDs, along with installation, programming, and troubleshooting is critical to efficient operation. The Variable Frequency Drive subject area covers these items.

 

Circuit Protection

Working with electricity is inherently dangerous, thus circuit breakers and protective relays are required to protect personnel. The Circuit Protection subject area covers both circuit breakers and protective relays, their functions, types, and methods of operation.

 

Transformers

The Transformers subject area covers power transformers and instrument transformers. The power transformer modules will discuss various designs and tests, while the instrument transformer module explains industrial types and designs of transformers.
