Features of AFR3-07 Arc Flash Detection Device
- Centralized information collection: AFR3-07 collects real-time data from all distributed recorders in the system to fully understand the operating status of the equipment.
- Rapid fault location: When an arc fault occurs, AFR3-07 can quickly determine the exact location of the fault, accurate to the compartment of the unit output line.
- Selective isolation: Based on the fault information, AFR3-07 can specifically cut off the fault line to prevent the accident from expanding.
- System integration: AFR3-07 can be seamlessly integrated with existing relay protection and automation systems to achieve a higher level of automation control.
- Extended functions: AFR3-07 provides a wealth of additional functions, such as remote operation (ROV), automatic transfer switch (ATS) blocking, self-diagnosis, oscillogram recording, and alarm log.
How does AFR3-07 Arc Flash Detection Device work?
The core of the AFR3-07 system is the central unit, which is responsible for receiving signals from each distributed recorder and performing comprehensive analysis. When an arc fault is detected, the central unit will quickly calculate the location of the fault point based on the preset logic and algorithm, and send isolation instructions to related equipment to achieve rapid fault removal.
