Why Choose this Training Course?
AC motors represent industry's workhorse in small, medium and large size applications. It is no exaggeration to suggest that more than 50% of the energy consumed worldwide is converted by AC motors into work and these motors are controlled by drives. These drives are ever increasing more intelligent, electrical and their monitoring and operation can be integrated with the plant's SCADA system. Understanding maintenance and troubleshooting procedures of such vital industrial equipment means that reduced downtime and increased productivity are the immediate benefits for the company and its management. Equally important, the protection requirements along with their function and integration with the overall system ensures that such expensive apparatus, requiring high capital investment, is well guarded against failures further offering safety for operations personnel as well. The training course addresses the three topics mentioned above for both AC motors and their drives.
What are the Goals?
The objectives of the training course are:
- To define the operation and construction of AC electrical motors and the electrical drives based on modern state-of-the-art inverter technology, and their characteristics that need to be matched with those of loads
- To review maintenance procedures both for motors and drives following well-established industrial procedures as outlined in standards
- To illustrate with troubleshooting methods for both motors and drives following methodologies that have been developed by manufacturers in order to reduce downturn time dramatically
- To analyse and familiarize on how to utilize single-line drawings and other documentation to successful perform commissioning, maintenance and troubleshooting
- To share case studies and learn from such experience
Who is this Training Course for?
Variable speed drive and troubleshooting is intended for:
- Electrical engineers
- Technicians and plant operations and maintenance professionals
- Team leaders and professionals in maintenance engineering departments
- Anyone who wishes to update their knowledge on one of the most important equipment combination, i.e. motor/drive and how to get the best of their trouble-free operation in the plant if possible
How will this Training Course be Presented?
The latest educational methods and strategies will be employed. The seminar is designed to maximize delegate benefit from the outset and any specific goals of each participant will be discussed to ensure needs are fulfilled as far as possible. Questions are encouraged throughout the day and at the daily wrap-up sessions. This provides opportunities for participants to discuss with the presenter and other delegates specific problems and appropriate solutions.
All delegates take away a detailed and comprehensive copy of the material presented; therefore minimal note taking is encouraged to ensure maximum participation and attention.
