Basic Design consideration: The power supply system shall be designed to provide safe, economical operation and ensure the safety Of equipment and persons. The power of the system should be economic, reliable, long service life, and panels should be simple in operation and maintenance. The following factors shall be taken into consideration while designing the Electrical system:
Safety: Personnel safety, the efficiency of operation
and precaution of equipment are the most vital factors
to be considered while designing the electrical
system.
Reliability: Reliability of electrical supply is essential for continuous operation. The electrical system shall be designed so that faults can be isolated with minimum disturbance to the system as well as a short time.
Easy operation: Simplicity of operation is a very important factor in achieving a safe and reliable electrical system. The operation should be as simple as possible to meet the requirement
V Voltage Fluctuation: Voltage shall be maintained within the equipment tolerance limit under all load condition in order to enhance the service life of electrical equipment.
Flexibility: Flexibility of the electrical system means the adaptability to meet the various requirement. utilization voltage, Equipment rating, space for additional equipment, capacity for increased load, spare capacity for future load.
Installation: Power installation shall be designed to give enough power, easy control of electrical devices. Materials, components, accessories used for installation shall be of identical type.
Maintenance: The electrical system shall be designed to allow easy maintenance without major interruption and disturbance of users.
Equipment: All equipment and
materials selected shall be well-known manufacture, spare parts are available,
manufactures are according to local and
international standard.
