Electrical Equipment Inspection Course
Introduction:
To successfully inspect and test electrical equipment, Electrical personnel must first fully understand the technology of the electrical equipment. After the successful start-up and subsequent continued operation, electrical equipment requires periodic inspection and testing. This will ensure the electrical equipment operates correctly so that production is maximized in a safe, cost-effective, and efficient manner. Delegates are encouraged to raise queries both during and at any time after attending the course and are also asked to bring with them any technical issues that they may have.
Course Objectives:
Participants attending this program will: On successful completion of this course, participants will have:
· A better understanding of maintenance purposes and types.
· A better understanding of inspection and testing methods
· A better understanding of the updated electrical condition monitoring
· A better understanding of troubleshooting procedures
· An improved capability in testing equipment
· A better understanding of safety issues.
· A refreshed outlook on reading electrical drawings
