Training Electric Motor Testing, Operation, Maintenance, Protection and Troubleshooting

INTRODUCTION

It is estimated that electrical drives and other rotating equipment consume about 50% of the total electrical energy consumed in the world today (and this figure increases to 70% if you only consid_pelatihaner industry.) The cost of maintaining electrical motors can be a significant amount in the budget item of manufacturing and mining industries. This course gives you a thorough understanding of electrical motor’s protection, control and maintenance and gives you the tools to maintain and troubleshoot electrical motors.

You will gain a fundamental understanding of the protection, control and maintenance of electric motors and drives. Typical applications of electric motors in manufacturing, materials handling, process control are covered in detail. The concluding section of the course gives you the fundamental tools in troubleshooting motors confid_pelatihanently and effectively.

OBJECTIVES

Upon successful completion of this course, the delegates will be able to: ·

- Apply and gain an in-depth knowledge on electric motor maintenance and troubleshooting ·
- Specify protection requirements for motors and maintain electrical motors ·
- id_pelatihanentify the speed control requirements for motors and discuss the essentials of motors and drives
- Enumerate the main issues with testing of motors to prevent motor bearing failure
- Troubleshoot and fix faults on motors and drives
- Discuss interface control circuits of motors with PLC’s/DCS’s
- Reduce downtime on electrical motors and improve plant safety · Develop plant throughput and reduce spares usage and requirements

WHO SHOULD ATTEND?

This course is valuable for those associated with the use of electrical motors in the industrial or automation environment. This course will also benefit those working in system design as well as site commissioning, maintenance and troubleshooting.
