Course Description
Transmission lines and sub-stations play an important role in the electrical power systems and exercise a vital influence on the reliability of services. Transmission lines are in continuous operation, therefore it is important to have a good design with perfect construction. It should facilitate easy maintenance without or with minimum interruptions. They require high flexibility to cope up with already existing control systems, available space, and limited downtime. In this course, participants will learn the constructional features, maintenance and routine testing of the transmission lines
What Do Participants Learn?
- Understanding the basic theories of electrical transmission lines
- Being familiar with the codes and standards of sub-stations and transmission lines
- Learning the technical configurations, and design practices of sub-stations and transmission lines
- Being familiar with construction and maintenance operations for sub-stations and transmission lines
Who Should Attend?
- Plant engineers
- Electrical maintenance
- Service technicians
- Contractors
- Energy auditors
- Anyone who is involved in planning, installing, and configuring electrical transmission lines
