Building Services system - Essay Example Distribution of electric power usually entails a complete distribution network. A complete distribution network entails several components including, a distribution substation, primary distribution feeder, a transformer, distributor and the service mains (Fink and Carroll, 2013). The transmitted electric power controlled in substations for primary distribution and use. The distribution system will take the model shown below: This power is then fed to the distribution transformer via the primary distribution feeders. The system will use a voltage of 2,400V. The distribution system to use in this project will take the form shown in the diagram below: The type of distribution system will be ring main electrical distribution system. This is preferred to the radial distribution system in that in case of a transformer failure or feeder failure, power is not interrupted. This is because one ring network of distributors gets power from several feeders. This implies in case one feeder fails to work, the others will still supply power and there would be no power interruptions. Addition this system consists of various section isolates at distinct points in the system. If a problem occurs in any of the isolates, then the others are available to supply power. This system will appear as shown in the figure below For emergency purposes the power system will include an independent reserve power source which will function in case of failure of the primary power source. This power source should be able to function for several hours before the main power supply is rectified. This alternative source of power will consist of an additional independent source of power complete with its independent controls ((Nasar and Unnewehr, 2012). This can be in form of engine driven generators and in this case they will have a voltage of 500 kW. The power system will consist of cables made of copper and aluminum
