Electrical Design and Calculations for Hotel Extension Project

This electrical engineering assignment focuses on the design and calculations for a hotel extension project. The solution addresses the requirements outlined in the assignment brief, which includes detailed circuit diagrams illustrating the three-phase 400 V supply system and earthing arrangement from the sub-station transformer to the charging unit, as well as manufacturer's data for luminaires, socket outlet layouts, and site plans. It also encompasses comprehensive calculations for design parameters such as total power for each room and common areas, circuit ratings, ambient temperature, cable types, and voltage drop. The assignment further analyzes earth loop impedance, maximum demand, and diversity factors, providing detailed calculations for each aspect. The solution provides a complete electrical design, including cable sizing, circuit protection, and load calculations, ensuring compliance with relevant standards and regulations.
