Electrical distribution needs are continuously evolving in residential, commercial, and industrial sectors. Owning to this, the demand for electrical power is on the rise, indicating the probability ...

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 ...

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, ...

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 ...

The comparison figure between no arc-fault state and arc-fault state under various type of loads, ranging from 30 W–60 W. An arc fault is an electrical discharge between two conductors due to poor ...

Although flawed in its execution, the addition of AFCIs to the 2002 Code highlights the importance of arc-fault protection. Circuit breakers and fuses are effective in preventing fires caused by a ...

Schweitzer Engineering Laboratories, Inc. (SEL) has announced the immediate availability of arc-flash detection capability in the SEL-751A Feeder Protection Relay, Schweitzer Engineering Laboratories, ...

Switchgear comprises electrical disconnect switches, fuses and/or circuit breakers that control, protect and isolate electrical equipment in electrical power systems. A switchgear fault (phase loss, ...

With increasing interest and demand for renewable energy sources, the market has seen a surge in the deployment of solar photovoltaic systems that convert sunlight to electricity. While new ...

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 ...
