Course Outline

After participating in this course, you will be able to:

• Select out of the various types of transformers, motors, variable speed drives, rectifiers, inverters, uninterruptable power systems (UPS), generators, circuit breakers, and fuses that are more suitable for your application.
• Use diagnostic testing, inspect with the awareness of common failure modes, apply advanced fault detection techniques, and recognize critical components that need more frequent attention.
• Save cost by enhancing reliability through predictive and preventive maintenance
• Increase availability of your equipment by appropriate commissioning using the understanding of commissioning requirements gained at the course
• Apply the new maintenance skills learnt at the course to minimize the operating cost and maximize efficiency, reliability and longevity
• Troubleshoot the non-performing equipment

Description

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, and fuses are of great concern to many industries. These objectives can only be achieved by understanding the characteristics, selection criteria, common problems and repair techniques for preventive and predictive maintenance. This seminar is a MUST for anyone who is involved in the selection, applications, or maintenance of electrical equipment. It provides the latest in technology. The seminar covers how this equipment operates and provides guidelines and rules that must be followed for a successful operation. Their basic design, operating characteristics, specification, selection criteria, advanced fault detection techniques, critical components as well as all maintenance issues are covered in detail.

Objective

To provide a comprehensive understanding of the various types of motors, variable-speed drives, transformers, rectifiers and inverters, uninterruptable power systems (UPS), generators, circuit breakers, and fuses to enable participants better specify, select, commission and maintain this equipment for use. To achieve reduced capital, operating and maintenance costs along with increase in efficiency.

Who Should Attend

Electrical and mechanical engineers, consulting engineers, electrical and mechanical technicians and technologists, project engineers, power plant managers, outage managers, maintenance and operations engineers, marine inspectors, computer technologist, procurement managers, technical sales managers, senior electricians and other technical personnel interested in electrical equipment.
 
Special Features

Included in the seminar is a book titled "Electrical Equipment Handbook" (600 pages) published by McGraw-Hill in 2003.
