Description
Arc fault protection is a relatively new technique employed for the clearance of arcing faults on low voltage panels, MCC’s, BUS bars and within metal clad switchgear and associated cable boxes.
Conventional current based protection techniques are at times challenged by the nature of arcing faults, and can result in slow protection clearance times. Slow protection clearance times increase the risk to nearby personnel and increase the degree of damage to plant and equipment.
By employing an optical detection technique, Arc Fault Protection results in fast clearance of arcing faults.
