摘要

减少清除时间是降低电弧闪光入射能级的关键因素。其他好处包括减少附带损害,缩短生产停机时间,并可能降低个人防护装备(PPE)要求。一种新型的快速电弧闪光检测方法利用长光纤光传感器比传统的继电器技术更快地检测和启动跳闸。本文讨论了应用实例以及两个记录的电弧闪光事件,其中实现了这种保护

Tripping with the Speed of Light: Arc Flash Protection
Reducing clearing time is a critical component in reducing arc flash incident energy levels. Additional benefits include reduced collateral damage, lower production downtime and potentially lower personal protective equipment (PPE) requirements. A novel method of fast arc flash detection utilizes long fiber optic light sensors to detect and initiate tripping faster than conventional relaying techniques. This paper discusses application examples as well as two documented arc flash events where this protection was implemented
