ARC FLASH PROTECTION AND RELAYS: Tripping With the Speed of Light
In conventional switchgear, reducing the clearing time is the most critical factor in lowering the incident energy level and hazard levels as defined by IEEE 1584 and NFPA 70E. Even a small delay on the order of a few milliseconds can significantly increase the amount of energy exposure to nearby equipment and personnel. Operationally, faster detection and fault clearing can reduce NFPA defined hazard levels, thereby reducing the required PPE suits required for working near energized gear. This presentation highlights how an arc flash can be optically detected by implanting "eyes" within the switchgear, literally "seeing" the fault rather than inferring about it based on secondary current or voltage inputs. Operating times of a few milliseconds have been achieved hereby significantly reducing the incident energy and hazard level. Two real-world arc flash events involving optical arc flash protection are discussed.
