Abstract:

The Student Industrial Work Experience Scheme (SIWES) is a compulsory programme designed by Nigerian Universities Commission (NUC) to expose students to more practical experiences in their various field, and to gain real-life experiences during the period.
This report gives the summary of the work done and experience gained during the course of my SIWES programme at Abuja Electricity Distribution Company, Gwagwalada-Abuja in the various units of the Technical Section: Dispatch and Operation unit, Maintenance unit, Protection, Control, and Metering (PC&M), Electric fitters and cable jointers.
