The arc protection system protects the operator from damage and reduces property damage in the event of an arc fault in the switchgear. RIZNER-EagleEye photoelectric arc protection system has been adopted by all major power systems and power companies in the country and its output trip command time is less than 3ms, which can protect the safety of workers even during installation or maintenance . The system consists of a main control unit, an arc unit, an arc expansion unit, a current unit, a current expansion unit, a power module, an arc sensor, an optical fiber, and a data line. Using advanced processor technology and a complete integrated control system, the arc light protection system is logically programmable and adapts to various operating modes of the bus. The output uses Triac technology to ensure that the circuit breaker in the switchgear receives a trip command in the shortest time.
