Course Description
The 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 ensure reliable and economical operation of power systems. This course 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.
