INTRODUCTION
Maximum efficiency, reliability and longevity of electrical equipment such as the various types of motors, variable-speed drives, transformers, generators, rectifiers, inverters, uninterruptible power systems, circuit breakers, fuses, and power station electrical and protective systems are of great concern to many industries. These objectives can only be achieved by understanding the characteristics, selection criteria, common problems and repair techniques, preventive and predictive maintenance.
-
COURSE OBJECTIVES
By the end of the course, you‘ll be able to:
- Understand diagnostic testing and inspection, advanced fault detection techniques, critical components, and common failure modes.
- Study selection criteria, commissioning requirements, predictive and preventive maintenance, reliability, testing and cost.
- Discover the maintenance required to minimize their operating cost and maximize their efficiency, reliability and longevity.
- Comprehend the hazards when working with electrical power systems.
- Perform electrical switching operations safely on all switchgears and associated equipment in preparation for maintenance tasks.
- Understand the correct methodology and safe operation when working on electrical equipment, switchgear on electrical distribution systems and all of the associated electrical plant and to be aware of all the associated hazards.
