Introduction:

Electrical Transmission system is the means of transmitting power from generating station to different load centers. Transmission lines represent a huge capital investment. The careful planning and design of electrical transmission lines are essential to insure reliable and economical operation of power systems.

This workshop will emphasize topics relevant to transmission lines Design, Operation and Protection. The installation of transmission lines will be also examined. Hands on practical examples will be provided to demonstrate many of the essential steps in transmission lines design and performance monitoring.

Objectives:

Upon successful completion of this training program, the participants will learn the following:

 The basic elements of electrical transmission lines
