AFSArc Flash Detection Sensors An arc flash is an electrical accident that creates a high-temperature explosion. It is an uncontrolled release of energy caused by an electric arc which exposes everything within its reach to a multitude of hazards such as: • extreme radiant heat (upwards of 20,000 degree Celsius), • a plasma ball (or fire ball), • molten shrapnel projectiles, • blinding light (ultraviolet and infrared), • a deafening sound (enough to rupture ear drums) and • dangerous vaporous gasses. An arc flash can happen during abnormal use due to a corruption of isolation, or in circumstances involving animals, flooding, vibrations, or corrosion. It can also occur during commissioning or maintenance, rendering equipment unusable and forcing costly downtime with serious economic consequences. Prevent accidents and protect your site with our arc flash protection solutions for both safety and productivity. Arc-flash detection technology significantly decreases the time it takes a relay to trip in response to an arc fault, which reduces hazardous arc-flash incident energy. FANOX combination of light-sensing technology with fast overcurrent protection allows high-speed tripping during arc-flash events without overtripping for external faults or adverse light conditions. • High-Speed Detection: Arc-flash light sensing and overcurrent protection detect arc-flash hazards and send a trip signal to the breaker in as fast as 4ms. • Lifesaving Protection: By reducing the energy of this explosions the injuries caused on the persons working on the surroundings. • Reduced Damage to Switchgear: With arc-flash protection, equipment damage is minimized during an arc-flash event, returning affected equipment to service faster and maximizing power system availability. • Coordinated Protection: The use of IEC 61850 GOOSE messaging allows coordination with upstream protection if a fault occurs. • Flexible Installation: Install into new switchgear or motor control centers. • Retrofit into existing equipment is also possible. • Quality, Reliability and Service.
