Course Description:

The safe and efficient operation of modern electrical equipment and control systems requires the successful testing, start-up and commissioning of this equipment or system to ensure the correct operation plus accurate troubleshooting and subsequent repair of this equipment or system to ensure continued productivity.

Delegates are encouraged to raise queries both during and at any time after attending the course. Delegates are also encouraged to bring with them any issues that they may have to this course.

Course Goal:

Following the attendance at this course, participants will return to their respective organizations equipped with new or refreshed skills to ensure that electrical equipment and control systems are tested and commissioned in a fashion that ensures reduced costs and or start-up delays plus identified faults or problems are repaired and the underlying causes are identified and eliminated to reduce further failures.

Course Objectives:

By the end of the course the participant will be able to:

1. Understand commissioning procedures
2. Understand troubleshooting procedures
3. Improve capability in the use of test equipment
4. Understand failure modes and failure analysis
5. Have a refreshed awareness of electrical safety concerns
6. Develop a structured approach to electrical commissioning, testing and troubleshooting plus provide methods/solutions for various electrical problems.
7. Maintain a continuing understanding of test equipment used for electrical commissioning and servicing
8. Understand the design, functionality and failure modes of electrical equipment and control systems.
9. Provide examples of successful commissioning and troubleshooting techniques and hands-on experience plus case studies and group problem solving exercises
10. Utilize single-line diagrams and schematics for troubleshooting.
11. Better understand standard work practices plus develop job plans, which assist in successful commissioning and troubleshooting.
12. Refresh the delegates’ knowledge of electrical safety.
