Course Description:

This Course covers important topics related to power distribution load. These topics include a functional description of distribution system, control, maintenance, and protection as well as the routine maintenance requirements of the overhead lines and underground cable. The course will include another objective for reduce costs and maximize reliability. Power factor improvement, which is the minimization of losses or loss reduction in power distribution system.

Course Goal:

To enhance the delegate knowledge, skills, and abilities necessary to properly measure power distribution load and specify its importance in power system operation and control
