This fault indicator is installed on overhead circuits, which is consist of monitoring circuits, circuit analysis algorithm, triggering circuits, wireless transmission circuit module and power circuit. This product is mainly used to transport the information of monitored short-circuit, earthing and load current etc. to overhead communication terminal through WI-FI model. Three fault indicators together is a group.
Short-circuit fault, adaptive without setting fixed value, single-phase earth fault
Load and fault current metering:
Adapt line load current and short-circuit fault current
Turnover and flash
Low Battery Alarm：
Alarm when battery lower than 2.8V
Information Remote Transmitting:
The information of faults and current etc. can be sent to communication terminal, which can support two-way confirmation function.
After fault clearance, automatic reset; Automatic reset, manual reset within the given time.
Self-Check: Reset self-check
Fluctuation of load, load switching, transformer no-load closing inrush current, switching inrush current line road and reclosing current etc.
Remove with Electricity
Long-term outdoor operation, the structure is made by rust corrosion materials
