5-Day Training Course
Course Overview
AC motors are essential to a wide range of industries, powering small, medium, and large-scale applications. It's estimated that over 50% of global energy consumption is converted into work by AC motors, which are controlled by drives. These drives are becoming progressively more advanced and electrical, and their operation and monitoring can now be integrated into a plant’s SCADA system. Gaining a comprehensive understanding of maintenance and troubleshooting for such critical industrial equipment results in reduced downtime and enhanced productivity for companies. Additionally, ensuring the proper protection mechanisms and their integration into the system safeguards these costly assets from failure, while also enhancing the safety of operations personnel. This Variable Speed-Drive Troubleshooting training course covers these key aspects for both AC motors and their associated drives.
Course Objectives
The objectives of this Variable Speed-Drive Troubleshooting training course are:
- To explain the operation and design of AC electrical motors and drives using advanced inverter technology, focusing on how to match their characteristics with those of the loads they drive.
- To review established industrial standards and procedures for maintaining both motors and drives.
- To demonstrate troubleshooting techniques for both motors and drives, utilizing manufacturer-developed methodologies to significantly reduce downtime.
- To provide hands-on experience with single-line diagrams and other relevant documentation, enabling effective commissioning, maintenance, and troubleshooting.
- To discuss case studies and share practical insights to enhance learning from real-world experiences.
Training Methodology
The latest educational methods and strategies will be employed. The Energy training course 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.
