Following the drawout circuit breaker a1 from the transformer, it is attached to a heavier, horizontal line. Leave this field empty if you're human:. You can change these settings at any time. On the 5kV side of this transformer, a disconnect switch is shown. The winding resistance, including the line resistance, are quite small in comparison with leakage reactance and shunt path which includes line charging and transformer magnetising circuit provide a very high parallel impedance with fault. Figure 1 — Simple single line diagram You can tell by the symbols that this single line diagram has three resistors and a battery. Provided you are able to locate and use the relevant symbols, you can incorporate them into a custom library, which can then be used in the same way as any of the existing default libraries.

The outgoing feeder supplies the input power to the consumer end. Although we do not know the exact function of the in this circuit, it is obvious that it is important to keep the equipment up and running. This circuit breaker is attached to a fused disconnect switch and it is connected to a step-down transformer. The load is assumed to be passive and are represented by a resistive and inductive reactance in the series. Reactance diagram is drawn by neglecting the effective resistance of generator armature, transformer winding resistance, transmission line resistance line charging and the magnetising circuit of transformers. Current transformer Represents current transformers mounted in assembled equipment.

Medium voltage motor starter The symbol is a combination of a drawout fuse, normally open contact switch and motor. Non-drawout circuit breaker Represents a fixed mounted low voltage circuit breaker. Notice the wire leading to the receptacle on the west wall is broken, this means the wire is concealed in the floor. Notice that all the equipment below the transformer is now considered low voltage equipment, because the voltage has been stepped down to a level of 600 volts or lower. It is very versatile and comprehensive because it can depict very simple , or a very complicated three-phase system. This over-simplified analysis of a one-line diagram gives you an idea of the kind of story such diagrams tell about electrical system connections and equipment.

Include trip setting for low voltage breakers. Electrical Diagram Symbols Use the Electrical diagram symbols to create an electrical diagrams effortlessly. Creating draft versions of single-line and schematic diagrams is part of the process of working out the final design aspects. Electrical elements such as circuit breakers, transformers, capacitors, , and conductors are shown by standardized schematic symbols. The rule-based design of Auto-Build can significantly reduce the time spent on creating a one-line diagram. Note: Each designer or engineer may call prints by different names or use schematics that are slightly different in style.

This means power is supplied to the ceiling fixture from terminal 4 of the service entrance, located in the lower right corner of the diagram. The connector endpoints turn red when the shapes are connected. Advantages: A wiring diagram is the most detailed and complex type of electrical print. Current transformer Represents current transformers mounted in assembled equipment. Reactance Diagram for the Power System The reactance diagram gives an accurate result for many power system studies, such as short-circuit studies, etc. You can enter shape data and add new data to a shape.

On the right side of the third area there is another fixed circuit breaker connected to the bus. This could represent a load center in a building that feeds power to the lights, air conditioning, heat and any other electrical equipment connected to the building. The equipment below the disconnect is at 5kV, since nothing indicates the contrary. If the resistance and reactance ignored errors up to 12% may be introduced. You can drag the built-in electrical symbols then connect them without a hitch.

Electrical Diagram Software Then you can use the built-in to prepare and present your electrical diagrams in only a moment. Conductor type, size, quantity, number per phase, length, magnetic or non-magnetic ii. In Visio when I am drawing an electrical diagram and using connectors, when the connectors cross one of them forms a small 'hump' to show they are not connected. The user can also add contouring as an option. Removable or drawout circuit breaker Represents a drawout low voltage circuit breaker. You can change these settings at any time. To explain this easier, we have divided the single line into three sections.

An important and frequent exception is an on only one or two phases of the system. This horizontal line represents an electrical bus, which is a means used to get electricity to other areas or circuits. Circuit breakers are represented by rectangular blocks. When interpreting a single line diagram, you should always start at the top where the highest voltage is and work your way down to the lowest voltage. But each serves different functions. The figure shown below represents the single line diagram of a typical block system. Now locate the second drawout circuit breaker b2.
