Abstract :
This paper presents a new, reliable solution using arc-flash light detection supervised using overcurrent protection to reduce the risk of an arc flash in low- and medium-voltage panels and switchgear equipment, thereby eliminating false trips from lighting and providing the fastest detection and tripping possible. The paper also presents the advantages of fast overcurrent detection combined with arc-flash measurement to produce a sensitive, fast, and secure tripping scheme.
