    摘要： An arc detection assembly (101) is provided and includes a first conductor (110, 163) comprising a first terminal end (111, 161), a second conductor (120, 165) comprising a second terminal end (121, 162), an enclosure (130) to partially enclose a space (131) in which the first and second terminal ends (111, 121, 161, 162) are engageable to form an electrical connection (102) and an optical detection system (150). The optical detection system (150) includes an optical element (151) within the enclosure (130) with a line-of-sight to an engagement of the first and second terminal ends (111, 121, 161, 162) and a sensor (152). The sensor (152) is displaced from the enclosure (130) and coupled to the optical element (151). The sensor (152) is configured to determine when the optical element (151) senses an arcing condition between the first and second terminal ends (111, 121, 161, 162).
