Course Introduction
The course covers transmission line aspects that influence maintenance and investment decisions and covers reliability measures used in the industry. The maintenance section provides inspection and diagnostic options, sample maintenance programing with cost and accomplishment reporting, industry practices, a method to evaluate maintenance program effectiveness and important condition information needed to manage line assets/components. The course includes strategies for sustainment investment planning that covers health indexing, condition based criteria, asset replacement optimization, criticality ranking of transmission lines and methods to improve reliability.
A component of power system
This course will cover the concepts involved in power transmission and distribution systems: Components of power systems; Transmission line as a component of power system; Line conductors; Line parameters and their calculations; Performance of transmission lines; Traveling waves on the transmission lines, Power limits of transmission systems, Voltage Control, Interference of power with communication lines
O.H.T.L An overhead power line is an electric power transmission line suspended by towers or utility poles. Since most of the insulation is provided by air, overhead power lines are generally the lowest-cost method of transmission for large quantities of electric energy. Towers for support of the lines are made of wood (as-grown or laminated), steel (either lattice structures or tubular poles), concrete, Aluminium, and occasionally reinforced plastics.
Course objective
- Become familiar with the basic operation, behavior, and modeling of transmission lines.
- Determine conductor sag, tension, and mechanical forces on overhead structures
- Describe performance and economic factors relevant to the specification of wood, steel, and concrete poles and structural components
- Determine insulation levels and select insulators, lightning arresters, grounding, and other
- Components coordinated to provide acceptable lightning performance
