Electrical Power Substation Layout, Design and Construction

COURSE DURATION: 5 Days INTRODUCTION: This course is aimed at introducing the power-substation layout and design to utility and industrial engineers. The course will cover substation layout, design, grounding and protection. The course will be supported by practical design examples. COURSE OBJECTIVES: To improve the skills of engineers involved in design, operation and maintenance of electric power substation. A degree in electrical engineering is recommended to gain maximum benefit from the course WHO SHOULD ATTEND? Engineers involved in design, operation and maintenance of power substations. A degree in electrical engineering is recommended to gain maximum benefit. MATERIAL LANGUAGE: PRESENTATION LANGUAGE: English English/Arabic

TRAINING METHODOLOGY: Each course participant will receive a copy of the comprehensive course notes. The presenter will discuss the topics using transparences, and videotapes. The course is designed to have an interactive format to maximize delegate participation. Questions and answers are encouraged throughout and at the daily sessions. Needs-Based case studies and examples will be discussed in problem solving workshop sessions. This gives participants the opportunity to discuss with other delegates and the presenter their specific problems and appropriate solutions. Only minimum note taking is encouraged to ensure maximum delegate attention during the course.
