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 ...

Arc-fault interrupters (AFIs) are starting to show up in the marketplace and are under consideration within NEC (National Electrical Code) regulations. They are the next big thing in circuit ...

Although new to the NEC, AFCIs are important for protecting against arc faults. Unsafe arc faults can occur as series or parallel arcs. A series arc can occur when the conductor in series with the ...

ArcCalc arc flash calculator software allows users to estimate incident energy level can categorize arch flash hazards at any point in a system. The software determines the arc fault clearing time for ...

The United States' National Electrical Code (NEC) recently expanded Arc-Fault Circuit Interrupter (AFCI) requirements (see "Arc-Detecting Circuit Breakers Will See Wider Use" at ...
