An arc-fault circuit interrupter (AFCI) or arc-fault detection device (AFDD) is circuit breaker designed to detect electrical arcs that could cause a fire. Loose wire connections can cause electrical arcing and ultimately enough heat to start a fire. In the US these circuit breakers have been...

Aerospace series - Arc fault circuit breakers, single-pole, temperature compensated, rated current 3 A to 25 A - 115 V a.c. 400 Hz constant frequency - Part 004: With signal contact - Product standard; German and English version EN 4838-004:2018...
a high-voltage electrical arc is produced that is either desirably, or by necessity, quenched. More particularly, the present invention relates to a composition to achieve arc-quenching and structural properties in devices such as circuit interrupters, high-voltage fuses, circuit breakers, and separ...
Moreover, fuses and circuit breakers are capable of preventing serious overload conditions, but they are generally ineffective to prevent electrical fires and other damage from accidental arcs and sparks which typically generate enough heat for a fire at electric current levels below the level at whi...
The occurrence of AF with circuit breakers inside sub-stations makes it possible to use the existing voltage transformers inside those substations to obtain voltage readings, which can be implemented in the inverse TCC of the overcurrent relay to obtain the least possible time in case of fault, ...
1 System Description Some applications in grid infrastructure require simultaneous measurements of signal and detection of fault conditions. This includes equipment such as arc fault circuit interrupters, transient fault recorders, arc flash sensors, breakers, and so on. While the fundamental signal is ...
