The Fundamentals of Overhead Transmission Line Design course from Siemens Power Academy TD provides participants with a fundamental understanding of the electrical and mechanical design of AC 69-765 kV transmission lines.
In PTEC 500 participants gain an understanding of the overhead line theory and application, including planning, design, construction, operation and maintenance.
- Overhead line design, including components, ROW, major considerations and constraints
- Typical tasks related to overhead line planning, design and construction
- Considerations in appropriate route selection, environmental licensing and impact mitigation
- Loading and strength design criteria: NESC deterministic based design and IEC reliability based design
- Conductors including steady-state, transient and dynamic thermal ratings, technical-economical selection, and bundling
- Catenary conditions, variations and calculations
- Electric field characterization, sources, management and mitigation
- Corona effects, including audible noise, radio and TV interference
- Magnetic field sources, formulas, management and mitigation
- Electromagnetic compatibility between OHTL and nearby facilities
- Basic concepts of structures and foundations
- Materials and design specifications of insulators, hardware and accessories •
- Voltage stresses (steady state, temporary and transient overvoltages) •
- Insulation coordination methods, characteristics and requirements •
- Overhead line electrical parameters, including line series impedance and line shunt admittance
- Thermal uprating and voltage upgrading, including techniques and economic feasibility analysis
Upon completion of this course, participants will understand how transmission lines are designed and how they fit into an integrated power system design.
The structure of the course is intended for engineers needing an overview of the important aspects and applications of transmission lines. Course structure This is a four-and-one-half-day course. Material is presented in both morning and afternoon sessions for a total of six hours of daily instruction. Standard course hours are 9 a.m. to 4 p.m. each day, except the last day, which concludes at noon.
