Electrical Maintenance and Inspection

(Electrical Troubleshooting Techniques)



Upon the completion of this course, the participants would be introduced to the different types of maintenance and inspection along with the different types of tests whether commissioning, routine, and failure tests. The participants will also be introduced to the most recent trending method of testing essential for identifying the failure/problems as early as possible. Also different causes along with root cause analysis will be introduced to the participants. The most wide spread of quality deterioration in power system are also presented in the course.
