COURSE OVERVIEW
It is estimated that electrical drives and other rotating equipment consume about 50% of the total electrical energy consumed. The variable frequency drive (VFD) industry is growing rapidly, and it is now more important than ever for technicians and maintenance personnel to keep VFD installations running smoothly
This outstanding seminar gives you a fundamental understanding of the installation, operation and troubleshooting of Variable Speed Drives (VSDs), electric motors & VFDs. Typical practical applications of VSDs in process control and materials handling such as those for submersible pumps, electric motors in mining and manufacturing and ventilations are covered in detail. You will learn the basic steps in specifying, installing, wiring and commissioning motors & VFD. The concluding section of the course gives you the fundamental tools in troubleshooting motors confidently and effectively.
