Building electrical distribution system diagram. Central station where power is generated by 3 phase alternators. Power plant electrical distribution systems gary w castleberry pe course description this one hour course provides an introduction to the design of electrical distribution systems found in electrical power generation plants. In order to transfer electrical power from an alternating current ac or a direct current dc source to the place where it will be used some type of distribution network must be utilized. At a tap off outlet or at the end of a busbar trunking run.
The voltage is then stepped up by suitable 3 phase transformers for transmission purposes. The electrical designer shall coordinate these requirements with the other disciplines to ensure these requirements are satisfied. It carries electricity from the transmission system to individual consumers. The distribution system can be divided in to.
In figure 1 cs. A short quiz follows. Primary distribution lines carry this medium voltage power to. Conference paper pdf available december 2006 with 4592 reads how we measure reads a read is counted each time someone views a publication.
The type of equipment utilized in the electrical distribution systems is discussed in terms of its design function role and backup capabilities. The vertical supply system rising mains. When dealing with a large power distribution system a special type of schematic diagram called an electrical single line is used to show all or part of the system. The system components vary depending on the size of the building so we will address systems for small and large buildings.
We will discuss the general principles for how electricity is moved from the utility lines to a convenience outlet in a room. Use drawing 2 typical building power distribution riser as a guide for building power systems. Coordinate with construction management the distribution concepts including load calculations calculated fault duties. Electrical power systems in buildings this article covers electrical distribution systems in buildings at a very basic level.
Represents the central station where power is generated by 3 phase alternators at 66kv or 11kv or 132kv or even 32 kv. Transfering acdc electrical power. Distribution inside large buildings in large buildings the type of distribution depends on the building type dimension the length of supply cables and the loads. Design consideration of electrical distribution and lightning protection systems for high rise building 111 busbar trunking systems are designed to withstand the effects of short circuit currents resulting from a fault at any load point in the system eg.
Electric power distribution is the final stage in the delivery of electric power. Electrical distribution systems are an essential part of the electrical power system. Figure 1 single line diagram of transmission and distribution network. The horizontal supply distribution at each floor level.
Electricity from the.
