Specific Electrical Design Requirements for Industrial Buildings

any designer wants to optimize his design by completely satisfying the individual needs of the building users, and in case of industrial building design , these individual needs will be generally as follows: 

1- Workshop and office flexibility:Upgradeability and reorganization, installation of new machines and modification of up to 50% of the workshop areas every year.

2-Production facility availability, continuity of service:In the metalworking industry for example, an unexpected break in production can result in a loss of up to 100 K Euros for each hour of downtime.

3- Time, investment and operating cost control controlling Energy, refurbishment and maintenance costs.

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

1-General distribution.

2-Sub-distribution.

3-Final distribution.

these three levels construct what we called ”  Power distribution architecture” which reviewed many times by the designer in order to get it more optimized to ensure that the industrial facility runs smoothly and operates to its maximum potential.

Each industrial site has its own particular needs and requires a specific type of power distribution architecture to achieve the following principles: 

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

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

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

The famous Power distribution architectures in industrial buildings will be as follows: 

1- “Radial branched” power distribution architecture 

2- “Dual-transformer shared” power supply distribution architecture. 

3- “Multiple-transformer shared” power distribution architecture
