Product Description
Overhead Line Remote Fault Indicators for Smart Grid
JYZ-FF-FI Overhead Line Remote Fault Indicators is usually used in 5~38KV overhead line power distribution network to monitor and detect short-circuit and earth fault. The fault signal is indicated by mechanical flag and three ultra-bright blinking LEDs with 360º sight. The fault information and load current value can also be uploaded to the SCADA by 2G/3G/4G networks.
The indicator can be mounted under live conditions with the help of an adapter and a hot stick. The parameters such as trip current level, reset time, blinking interval, etc., can be read and adjusted by a bidirectional wireless tool. Battery low warning can be distinguished and indicated separately by red mechanical flag.
The short-circuit and earth-fault indicator type JYZ-FF-FI V1.0 consists of:
1*PCS DCU: Transmit fault signal and load current value to SCADA
3*PCS indicators: short-circuit and earth fault detection and indication

Typical Application
1.Excellent Ultra-Low Power Design, Effectively Extend Product Life
The ultra-low power consumption design combined with software and hardware can meet the requirement of working for more than 15 days without light.
2.Remote Device Configuration, Remote Upgrade,Greatly Improving Management Efficiency
There's no need to be on site, user can configure the device remotely, including setting the operating parameters, such as heartbeat interval, remote measurement upload time interval, transient failure return time, permanent fault recovery time, etc. Meanwhile, it also supports remote update and remote program maintenance, which greatly improves management efficiency.
3.Power Self-sustained Solution
Overhead fault indicator takes power from the line. When the load current is over 10A, it will not consume the battery power; fault indicator could work for more than 10 years maintenance-free.
4.Rugged Design, Fully Sealed Structure, Protection IP68 Level Long-term Outdoor Maintenance-free Operation
The overhead fault indicator is rugged designed, and the protection grade can reach IP68. It is suitable for long-term outdoor operation in harsh conditions and can be installed and disassembled with live power.
5.Identify Fault Type on Site
Indication of different kinds of fault (eg. Transient short circuit, permanent short circuit, earth-fault, low battery alarm) by different colors of LED blinking.
