Transmission and distribution networks - Basics Part I

This Transmission and Distribution Networks – Basics Part I course provides a clear introduction to the fundamental concepts of electrical power transmission and distribution systems. It explains how electrical energy is generated, transmitted over long distances, and distributed safely to consumers. Participants learn about transmission lines, distribution feeders, substations, transformers, switchgear, and other essential network components. The course covers basic electrical parameters such as voltage, current, power, power factor, and frequency in power networks. It introduces different transmission and distribution network configurations and their applications. Participants gain an understanding of overhead lines, underground cables, conductors, insulators, and supporting structures. The course also discusses basic voltage regulation, power losses, and efficiency in electrical networks. Fundamental concepts of load characteristics, load demand, and network planning are explained in simple terms. Practical examples help participants understand the operation and interconnection of transmission and distribution systems. This course builds a strong foundation for further learning in power systems, grid operation, protection, and electrical network design.
