Electrical installation & energy efficiency

any designer wants to optimize his design for industrial buildings by completely satisfying the users’ individual needs for these buildings which are: 

1- Workshop and office flexibility.

2-Production facility availability, continuity of service.

3- Time, investment and operating cost control.

these needs must be satisfied in the following three levels of electrical design for power distribution architecture which are:

1- General distribution.

2- Sub-distribution.

3- Final distribution.

Actually, Each industrial site has its own particular needs and requires a specific type of power distribution architecture based on the following principles: 

1- Cost optimization, which is closely, linked to the location of the MV/LV substations, 

2- Availability, which is primarily governed by the higher levels of the architecture, 

3- Flexibility, which is based mainly on the sub-distribution and final distribution design.

These principles can be applied in different types of power distribution architecture, especially in the common three types which are: 

1- "Radial branched" power distribution architecture,

2- "Dual-transformer shared" power supply distribution architecture,

3- "Multiple-transformer shared" power distribution architecture.

the first type of power distribution architecture; "Radial branched" was explained before in a previous topic and today I will continue explaining the other two types as follows: 

This power supply distribution architecture meets the needs for increased flexibility and availability for all industrial buildings.

The electrical design levels in this power distribution architecture will be as follows:
