Course Description
Power plant is critical plant where cited plant component like Power generators , transformers , Motors , Transmission Line , cables (Above Ground Underground Cables ) ,…..are highly specialized pieces of equipment. Individuals who work with them on a regular basis should have adequate training to properly select, design and evaluate the condition of the machine, as well as have the knowledge and expertise to fix any problems they find.
This course is designed to provide participants with a comprehensive understanding of Fundamentals of Overhead Transmission Lines Training used in electrical power systems. It covers various aspects including design principles, specifications, operation, and troubleshooting techniques. Participants will gain knowledge and skills necessary to effectively design, install, operate, and maintain power cables and transmission lines.
The main aim of this course is to empower the participant’s understanding of selection, installing , inspection of power distribution Overhead transmission lines . The participant will exit the course with greater ability to analyze common power Overhead transmission lines circuit problems. The participant will also have a stronger understanding of distribution system Installation & Maintenance and power system component equipment operation, troubleshooting.
