Course Description

It is estimated that variable speed drives and other rotating equipment consume about 50% of the total electrical energy consumed in the world today. The cost of maintaining variable speed devices can be a significant amount in the budget item of manufacturing and mining industries. This workshop gives you a thorough understanding of variable speed device’s working, maintenance and failure modes and gives you the tools to maintain and troubleshoot variable speed devices. You will gain valuable insight into the selection of the protection necessary to ensure your devices are protected against fault conditions, so as to ensure reliability and long life. Typical applications of variable speed devices in mining, manufacturing, materials handling and process control are covered in detail.
