COURSE OVERVIEW:

The operation of high-voltage transmission lines is a complex task that requires balancing load demand with the physical and environmental constraints of the overhead and underground network. This course provides a technical exploration of transmission line mechanics, focusing on the principles of power flow, stability, and asset management. Participants will explore how transmission lines interact with the wider grid, ensuring they can manage the infrastructure that forms the backbone of the energy sector.

The scope of this training addresses the practical aspects of transmission line operation, including sag and tension management, insulator performance, and corona loss mitigation. It covers the technical nuances of line protection schemes, such as distance relaying and tele-protection, which are vital for isolating faults across long distances. The curriculum provides a detailed focus on the inspection and maintenance of towers, conductors, and right-of-way (ROW) environments to ensure continuous service.

Coverage includes the implementation of modern monitoring technologies, such as drones and LiDAR, for line surveys and fault location. Attendees will learn to manage the risks of environmental factors like lightning strikes, icing, and wind-induced galloping on line stability. By combining theoretical electrical engineering with practical field operation strategies, the course equips professionals with the expertise required to maintain a reliable and efficient high-voltage transmission network.

COURSE OBJECTIVES:

After completion of this course, the participants will be able to:

• Explain the fundamental components of overhead transmission lines.
• Analyze the electrical parameters: Resistance, Inductance, and Capacitance.
• Calculate line losses, voltage drop, and power transfer limits.
• Manage conductor sag and tension for various weather conditions.
• Identify and mitigate corona discharge and radio interference.
• Select appropriate insulators based on voltage and pollution levels.
• Interpret and troubleshoot transmission line protection schemes.
• Utilize LiDAR and drone technology for line inspections.
• Implement effective right-of-way (ROW) and vegetation management.
• Analyze the impact of environmental factors like wind and ice on towers.
• Manage the maintenance of underground high-voltage cable lines.
• Execute safe procedures for live-line and dead-line maintenance.

TARGET AUDIENCE:

This course is intended for Transmission Engineers, Grid Operators, Asset Managers, and Senior Maintenance Teams responsible for HV networks.

TRAINING COURSE METHODOLOGY:

A highly interactive combination of lectures, discussion sessions, and case studies will be employed to maximize the transfer of information, knowledge, and experience. The course will be intensive, practical, and highly interactive. The sessions will start by raising the most relevant questions and motivating everybody to find the right answers. The attendants will also be encouraged to raise more of their questions and to share in developing the right answers using their analysis and experience. There will also be some indoor experiential activities to enhance the learning experience. Course material will be provided in PowerPoint, with necessary animations, learning videos, and general discussions.

The course participants shall be evaluated before, during, and at the end of the course.

COURSE CERTIFICATE:

National Consultant Centre for Training LLC (NCC) will issue an Attendance Certificate to all participants completing a minimum of 80% of the total attendance time requirement.
