A short circuit is an abnormal connection between two nodes of an electric circuit intended to be at different voltages. This results in an electric current limited only by the Thévenin equivalent resistance of the rest of the network which can cause circuit damage, overheating, fire or explosion.
The special cases of open circuit and short circuit lines are of particular relevance to stubs. Reflections cause standing waves to be set up on the line. Conversely, standing waves are an indication that reflections are present. There is a relationship between the measures of reflection coefficient and standing wave ratio.
For example, a short circuit is a fault in which a live wire touches a neutral or ground wire. An open-circuit fault occurs if a circuit is interrupted by a failure of a current-carrying wire (phase or neutral) or a blown fuse or circuit breaker. In three-phase systems, a fault may involve one or more phases and ground, or may occur only ...
A transient fault is a loss of power typically caused by a fault on a power line, e.g. a short circuit or flashover. Power is automatically restored once the fault is cleared. A brownout is a drop in voltage in an electrical power supply. The term brownout comes from the dimming experienced by incandescent lighting when the voltage sags.
A different form of short-circuit testing is done to assess the mechanical strength of the transformer windings, and their ability to withstand the high forces produced if an energized transformer experiences a short-circuit fault. Currents during such events can be several times the normal rated current.
The Tesla founder’s son, whose name is pronounced “ex-ash-ay-12” and who goes by “X” for short, has become a regular on the Trump/Musk circuit of late: carried on his dad’s shoulders ...
This type of arc flash mitigation device operates rapidly within a few milliseconds, creating a three-phase short-circuit to ground, which safely redirects fault currents away from the location of the arc flash. Upon activation by an external relay, a fast-moving contact pin makes physical contact with the energized bus, creating the short circuit.
When it comes to the supply chain, the U.S. -- and indeed, the world as a whole -- is experiencing a perfect storm. Evidence of a bottleneck of goods is everywhere you look, from shipping delays ...
