Working Principle of AFR3-06 Arc Detection Device
AFR3-06 consists of multiple arc fault recorders for fiber optic sensors and arc fault sensors and one (or more) central unit. The arc fault recorders monitor the equipment’s operating status in real-time and immediately send a signal to the central unit once an arc fault occurs. After receiving the signal, the central unit quickly locates the fault point and issues a command to isolate the faulty equipment, thereby protecting the entire system.
