How can a power distribution board be used in high rise buildings?
Larger power distribution board. In high rise buildings were stories are let separately (metering is at central point at ground floor). Smaller size of cables can be used (easy installation). In the case of a fault in arising main, only one story is effected. Different loading of the individual floors can not be balanced out.
What type of distribution system is used in large buildings?
In large buildings the type of distribution depends on the building type, dimension, the length of supply cables, and the loads. The distribution system can be divided in to: The vertical supply system (rising mains). The horizontal supply (distribution at each floor level).
What is the power supply in Baghdad?
The power supply to the city of Baghdad is provided basically from two main substations of 400/132 kV (Baghdad East and Baghdad west), which in turn supply many substations of 132/33 kV (or 132/33/11 kV) distributed geographically throughout the city. A schematic diagram showing the structure of this system is given in Fig.1.
What type of supply system do I Need?
The vertical supply system (rising mains). The horizontal supply (distribution at each floor level). In most cases a high voltage supply and transformer substation is required. Normally HV switchgear and installed at ground floor ( or basement ). However, air-conditioning equipment and electric kitchens).
Do consumers tolerate short time power interruption in power supply?
These consumers tolerate short time power interruption in power supply as it dose not cause damages mentioned above. In this system, separate feeders are radiated from a single substation and feed distribution transformations from one end only.
How many cubicles can a substation hold?
These substations are provided with three compartments: It is placed at one side of the substation, and has an independent access through a double-sided door with a specially designed lock. It has the capacity to hold up to three cubicles. 1000 kVA). this compartment is removable to enable transformer installation on site.
