short-circuit device
1short-circuit — short circuits, short circuiting, short circuited 1) V ERG If an electrical device short circuits, a wrong connection or damaged wire causes electricity to travel along the wrong route and damage the device. Carbon dust and oil build up in large… …
2Short circuit — A short circuit (sometimes abbreviated to short or s/c) allows a current along a different path from the one intended. The electrical opposite of a short circuit is an open circuit , which is an infinite resistance between two nodes. It is common …
3Prospective short circuit current — The prospective short circuit current (PSCC) is the highest electric current which can exist in a particular electrical system under short circuit conditions. It is determined by the voltage and impedance of the supply system. It is of the order… …
4Conditional short circuit current — is defined as the value of the alternating current (a.c) component of a prospective current, which a switch without integral short circuit protection, but protected by a suitable short circuit protective device (SCPD) in series, can withstand for …
5circuit breaker — cir cuit break er, n. (Elec.) A device contained within an electrical circuit designed to interrupt the circuit when the current exceeds a preset value; it is sometimes called a {contact breaker}. Its function is to prevent fire or damage to the… …
6Circuit breaker — For other uses, see Circuit breaker (disambiguation). An air circuit breaker for low voltage (less than 1000 volts) power distribution switchgear …
7Circuit theory — For the theory of monetary economics, see monetary circuit theory. Circuit theory is the theory of accomplishing work by means of routing matter through a loop.[citation needed] The types of matter used are: In electronic or electrical circuits:… …
8circuit breaker — 1. Elect. Also called breaker. a device for interrupting an electric circuit to prevent excessive current, as that caused by a short circuit, from damaging the apparatus in the circuit or from causing a fire. 2. any property tax relief measure… …
9circuit breaker — cir′cuit break er n. elm a device for automatically interrupting an electric circuit to prevent excessive current, as that caused by a short circuit, from damaging the apparatus in the circuit or from causing a fire • Etymology: 1870–75, amer …
10Circuit quantum electrodynamics — (circuit QED) provide the means to study the fundamental interaction between light and matter. As in the field of cavity quantum electrodynamics a single photon within a single mode cavity coherently couples to a quantum object (atom). In… …
