Short Circuit Drawing
Electric current takes the path of least resistance so in a short circuit the current will bypass other parallel paths and travel through the direct connection.
Short circuit drawing. Short circuit is unintended connection between two terminals which are supplying power to the load it can happen both in ac or dc circuit if it is an ac supply then short circuit can trip the power supply of whole area but there are fuses and overload protection circuits at many levels from the power station to the house. The term short circuit is most commonly used by electricians to refer to the situation in which a hot wire carrying live current touches a neutral wire when this happens resistance lessens instantly and a large volume of current flows through an unexpected pathway. The opposite of a short circuit is an open circuit which is an infinite resistance between two nodes. This would generate an excess of voltage streaming and cause excessive flow of current in the power source.
A short circuit is a direct connection between two points in a circuit that aren t supposed to be directly connected such as the two terminals of a power supply. The short circuit value at different points in the system is essential data in defining the cables busbars and all breaking and protection devices as well as their settings. When this classic short circuit occurs sparks sometimes fly you may hear crackling and sometimes smoke and. Short circuit current at a given point in the system is expressed as the rms value isc in ka of its ac component.
The circuit diagram of the short circuit test is shown below. A short circuit is when there is a low resistance connection between two conductors that are supplying electrical power to a circuit. What are the. The electricity will flow through a short route and cause a short circuit.
Definitions short circuit current diagram. Short circuits are another matter entirely. The low voltage source is applied across the secondary winding which is approximately 5 to 10 of the normal rated voltage.
