Table 1-1 List of the system constraints

Standards: This project will follow the standards and regulations of Kahramaa. These standards will be applied for electrical installation in the high-rise building. In addition, they will be used for designing a protection system and a substation to supply electricity for multi-storey building. Moreover, the British standards will be applied if it is mentioned in Kahramaa to return to them.

According to Kahramaa standards the rated voltage is 415V three-phase and 240 V single-phase, while the nominal frequency is 50 Hz. However, all standard and regulations mentioned in Kahramaa low voltage electricity and water insulation manual will be applied [5].
