Variable Frequency Drive Training

Variable Frequency Drives and Electric Motor Control

THIS 2-DAY VARIABLE FREQUENCY DRIVE TRAINING COURSE COVERS THE MOST IMPORTANT ASPECTS RELATED TO THE PROPER INSTALLATION, COMMISSIONING, TESTING AND MAINTENANCE AND OPERATION OF VARIABLE FREQUENCY DRIVES IN THE DISTRIBUTION SYSTEM.

This Variable Frequency Drive training course introduces the student to the world of variable frequency drives and their applications in industrial plants and commercial buildings. This electrical training course will introduce students to the upstream and downstream issues involved with variable frequency drives (VFDs) and the reasons for their application in controlling the rotational speed of motors and other electrical equipment. While most control circuits used in industrial or commercial applications still use mechanical operating systems, the application of VFD’s is increasing as a way to reduce power consumption and other operating costs.

This course will provide an overview on the Distribution System from the Point of Common Coupling (Incoming Utility Power Connection Point) right down to the connection location of the motor(s). The student will be made aware of all the installation guidelines needed to ensure a successful installation of VFDs.
