Arcs are visible plasma discharges caused by electrical current passing through a normally non-conductive medium such as air. This phenomenon occurs when the current ionises gases in the air, ...

Residential electrical branch circuit breakers incorporate electronic and electrical technology in Arc Fault Circuit Interrupters that can turn off power to prevent fires if arcing occurs. This ...

Arc fault detection is a critical issue in modern power and photovoltaic (PV) systems owing to the significant safety risks posed by unintended electrical discharges. These faults, occurring when ...

2011 NEC Section 690.11 requires detection and interruption of “arcing faults resulting from a failure in the intended continuity of a conductor, connection, module, or other system component.” This ...

Researchers from China's Tianjin University and inverter manufacturer Ginlong Solis have developed a novel AI-based method for DC arc detection in PV systems. A DC arc occurs in PV arrays when there ...
