Electrical engineering design is carried out by an electrical engineer whose duty is to produce a draft that ensures that electricity is generated, transmitted and distributed efficiently, making use of the clients specifications and also utilizing international codes and standards as guidelines. The engineer takes into consideration; the type of facility to be designed, the location and its environmental conditions. The design is aimed at minimizing operating cost, maximizing power quality and ensuring safety at all levels.
1. EQUIPMENT SIZING AND RATING
All the equipments in the facility that require an external power source to function have to be sized to determine the power requirements of the specific equipments so motors and cables that can sufficiently transmit and distribute power to each equipment is provided.
This shows all the information and calculation that was used to obtain the particular design and it basically contains 1. Scope 2. Reference materials 3. Electrical loads 4. Appendix Examples of electrical engineering design calculation notes include : Power Balance Load Flow Earthing Systems Motor Starting Studies
